economic liberalism

Last week David Cameron unveiled the Tories' latest wheeze - the idea that those able to work but not doing so and claiming benefits should be forced into some form of "community work" to justify their benefits after a period. Two years on Job Seeker's Allowance is enough to prove someone either unemployable or simply lazy goes the line. In some quarters it was hailed, not doubt with the help of the party spin machine, as an end to the "something for nothing culture" that pervades the benefits system.

Now, set aside for the moment the debate about whether this is some form of slave labour, or a way of quietly abolishing the minimum wage (although this latter begs the question as to whether it is right that only the unemployed should be allowed to opt for jobs below the minimum wage or whether only community groups should be allowed to pay below the minimum wage). We do in fact already have a deep rooted "something for nothing culture" in this country and seventy per cent of us, those who live in houses they actually own, believe that they have an absolute right to this "something for nothing" and over the past decade or so of rising land values, pushing house prices through the roof, they have benefitted massively.

Indeed, most of us can probably point to people who, over the past few years, have seen their wealth in the form of property, the value of their home, increase by more than their annual income from working. Equally in the same measure, we can probably point to people who, because they weren't lucky enough to have got in on this rat race of home ownership, have seen their chances of ever doing so fade as the multiple of income they now have to pay increases beyond any prudent lender would allow them to borrow.

Of course there are many who would point out that this wealth only really exists on paper; that for as long as we need a place to live the current value of the spot we own is of little meaning, as everywhere else is rising or falling in similar proportions and if we want to move we'll still need to cash in what we have and perhaps pay even more for our next home. And that this paper value is only of any use to us when we reach our final resting place or, if we are sensible about it, when we decide we no longer need the property we bought when we wanted to get the kids into a good local school or be close to the fast rail line into work or whatever and "downsize" or "escape to the country", hopefully giving us a pot of cash in the process to make our final years more comfortable.

Some may even suggest that it has been an unquestionable benefit to the economy as people have cashed in through equity release schemes and re-mortgaging to supply them with cash which has kept the consumer demand in the economy going when other countries' economies may have suffered recession and stagnation. As we face a possible slide in property values of course some of these people may find out to their cost that funding their lifestyles from the value of their home was a bad idea and that the only people, longer term, to benefit, are the bankers who they will be paying for their profligacy for years to come.

But I do not want to focus on whether housing is a good or bad investment: clearly in many cases it is a good one as the market is currently structured, albeit an unorthodox sort of investment - you don't usually get to consume something that continues to rise in value. I want to show you that it is an inequitable investment, that it is "something for nothing" and that the least well off pay for home owners' prosperity in a very real way even if that prosperity is mostly "on paper" for most of the time.

LAND: A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure. Carried to its logical conclusion, it means that some have the right to prevent others from living; for the right to own implies the right exclusively to occupy, and in fact laws of trespass are enacted wherever property in land is recognised. It follows that if the whole area of terra firma is owned by A, B and C, there will be no place for D, E, F and G to be born, or, born as trespassers, to exist.
Devil's Dictionary, 1911, Ambrose Bierce

If we go back to first principles, to what philosophy seems to call the "state of nature", some of the most fundamental assumptions are still as valid today as they ever were. We only have one planet. So every living soul born on that planet has to share it with everyone else - there is, as yet, no escape from that. The corollary of that is that everyone born on this planet has a right to a share of the planet - an absolute right, a "birthright". Some things we are completely dependent on the planet to provide for life...we need a place to live; humans cannot wander all the time, we need to sleep and to sleep we need to stop wandering. Similarly we need air, water, sustenance and again, we know ultimately of no way of producing these artificially without involving the natural resources of the planet.

Now, in that state of nature, if there's nothing else, like society, to hold us dependent on one place for any of these requirements of life, we would all be able to spread out, and appropriate as much land as we need to sustain our own lives, as individuals or families without negatively affecting anyone else. This "free land" gives us freedom, independence and life. Even today, in "overcrowded" England, as many would have us believe, there's enough land area for us all, every man, woman and child of us, to have just over a half an acre each - globally there's about 5.5 acres each of land mass. Naturally, not all these acres are fertile and even if they were, subsistence farming does not create wealth. Human growth and ingenuity requires that we specialize and socialize, which will usually mean also urbanize. Until we invent Scotty's instant transporter we have to make do by fitting many more people into urban land simply so they can be close enough to the facilities they need, and we need them to have - such as workplaces, to make working there viable.

But why should any of this mean that we give up our birthright, our common and individual birthright, to share equitably in the wealth of the planet itself? After all, you, the home owner, need me, the tenant, to work at whatever it is I do to provide you and everyone else with goods and services the economy demands. I, to fulfill my potential and contribute to the fullest to society, am better off working at what I do than ever I would be tending half an acre of small-holding (especially if you have seen my attempts to grow a window box of herbs!). But where is that birthright? Well, it is in the value of the location on which your home, office, factory or whatever stands, and it is created by and belongs to all of us!

Not one solitary square inch of English soil remains unclaimed on which the landless citizen can legally lay his hand without paying a toll to somebody; in other words, without giving a part of his own labor or the product of his labor to one of the squatting and tabooing class in exchange for their permission (which they can withhold if they choose) merely to go on existing upon the ground which was originally common to all alike, and has been unjustly seized upon (through what particular process matters little) by the ancestors or predecessors of the present monopolists.
"Individualism and Socialism," Contemporary Review (1889), Charles Grant Allen

You see, even John Locke, arch-defender of private property, recognized that there were limits to the right to appropriate land - the stuff of nature that exists in a finite amount yet which we all need to survive. Robert Nozick coined the phrase the "Lockean Proviso" for the principle that however much you take and occupy for yourself equity demands that you leave "enough, and as good, in common...to others". A hundred and thirty years after Locke wrote his Second Treatise of Government, David Ricardo formulated his Law of Rent, and a few years later Johann Heinrich von Thunen demonstrated the practicalities of this using data from his family estates.

It would be too much here to explain all of these ideas in any detail, but what they all amount to is that as you get closer to the social, employment, commercial facilities that more people need access to the land value surrounding those facilities absorbs some of the wages of all who need to access those facilities and is reflected in higher land values. So you see, this is not a fight just between the thirty per cent who don't own their home and the seventy that do. Many of that seventy per cent are also affected by this accretion of wages to land values. Think of it this way - you may have to settle (and you may enjoy it!) for buying a property several miles away from your work place or the nearest high quality commercial centre because all the property closer is too expensive. All those land owners that you pass on the way to work are gaining from your and the many other people in the same situation unfulfilled need.

Even more galling is that if we all happen to have the same incomes - you having managed to grab your slice of land at some earlier stage when it was less popular and therefore cheaper - we are taxed at the same level on those incomes. In turn both of our sets of taxes are used to invest in even more facilities that contribute to those land values. The person owning property closer to the "action" is gaining from all of our taxes disproportionately from those living further away. Similarly, the person owning property closer to the action has no incentive at all to release that location for others who may need it more at different stages in their lives, because they are continuing to gain from it and from those for whom it may now be a more appropriate place to settle. They are, quite literally, getting something for nothing, on their part at least. Something from the needs and activities of all of us that could make as good or better use of that location.

Ricardo's Law: House Prices and the Great Tax Clawback Scam (Fred Harrison)

If you are interested in exploring this further, I would recommend a recent book by a chap called Fred Harrison, called "Ricardo's Law: House Prices and the Great Tax Clawback Scam (Why Tony Blair's Project Failed)" in which he shows that all the arguments about Londoners and people in the south east subsidizing other areas of the country via the tax and regional grant system pales into insignificance when you realize that the overall effect of that spending is to make property values in the south east and London increase faster.

Harrison concludes, as I do, that the entire tax system should therefore be based on the values created by all of us but currently "enclosed" by land owners. A hundred and more years ago the American self-educated economist, Henry George, encapsulated this into his idea of a "single tax" - that all the rental value of unimproved land in any jurisdiction should be collected by the state, whose fiscal program should be strictly limited to the amount that can be collected this way. He preferred, as again do I, that the state would do very little but turn that money around and dole it out to everyone, equally, in the form of a Citizen's Income; if you like, a dividend from what we all invest by creating that land value in the first place - our common birthright. At the same time, our average tax bill per individual would be halved, our economy would grow by around a third and we'd have a much more equitable society.

"The value of land rises as population grows and national necessities increase, not in proportion to the application of capital and labour, but through the development of the community itself. You have a form of value, therefore, which is conveniently called 'site value,' entirely independent of buildings and improvements and of other things which non-owners and occupiers have done to increase its value - a source of value created by the community, which the community is entitled to appropriate to itself. …In almost every aspect of our social and industrial problem you are brought back sooner or later to that fundamental fact."
[Mr. H.H. Asquith, at Paisley, 7th June 1923]

"We hold, as we always have held, that, so far as practicable, local and national taxes which are necessary for public purposes should fall on the publicly-created value rather than on that which is the product of individual enterprise and industry. That does not involve a new or additional burden on taxation, but it would produce these two consequences - first of all, that we should cease to be imposing a burden upon successful enterprise and industry; and next, that the land would come more readily and cheaply into the best use for which it is fitted. These two things would be two potent promoters of industry and progress."
[Mr. H.H. Asquith, at Buxton, 1st June 1923]

One of the most common points of disagreement between, let's call them "state-interventionists" and "non-interventionists", is the claim that "non-interventionism" would leave the poorest in society on the scrap heap with no welfare, no support. That the much vaunted idea of "non-interventionists" that "private charity" or "voluntary co-operation" would take the place of state welfare is just an impossible pipe dream. So determinedly do "state-interventionists" believe their own claims that they frequently castigate "non-interventionists" as heartless uncaring selfish individualists who would rather see others die than pay taxes. One quote from a Lib Dem Voice "discussion" just today will give you the general idea:

"Well none of them [Libertarians] are serious, because it an incoherent philosophy....send the kids back down the mines, it’s only a lifestyle choice."

And to an extent, I used to believe that propaganda. As a geo-libertarian of course I do have an answer of sorts - the basic income derived from land user fees (which would on their own create an almost unimaginably more equitable society in any case) would cover the basics of life for everyone, and give everyone an incentive to top it up with as much or as little work as they can manage.

But a recent discussion on a "non-interventionist" mailing list I've been frequenting recently has challenged the basic assumption of this debate for me. Would people really not contribute voluntarily to the upkeep of others if you don't have a government apparatus threatening them with the confiscation of their property and ultimately the loss of their freedom unless they pay their taxes?

It is a strange proposition. Governments for at least the last sixty years have been supporters at some level or another of some form of state welfare. They may argue about how much is appropriate but the fact is, people have overwhelmingly voted for a state that takes money from you in order to give some of what's yours to someone deemed "less fortunate". We even have a cliche about the inevitability of death, and taxes.

We have tens, maybe hundreds of thousands of people who do voluntarily give up their time to care for another. Most people are someone's relative, someone's friend, someone's colleague. And whilst I recognize that some do not have such support networks and would still require some form of collective support, most people do not want to see their friends and relatives on skid row or worse.

One has to wonder whether the interventionist route actually makes things worse. And in how many ways. When we look at our pay packets do we not think often that we've given quite enough for the support of others through our taxes thank you very much. National Insurance and Income Tax between them effectively make the worker near forty per cent worse off. I know what I would do with an extra forty per cent each month. It would pay the interest bill on the piece of land we have just acquired for our first Community Land Trust for a start.

Other taxes and protectionist policies keep the prices we pay for basics artificially high and create incentives for companies to produce cash cows rather than exciting developments. I'll bet if we didn't guarantee one pharmaceutical company a contract for however many millions of doses of Metformin diabetes pills every year a dozen others would have put the effort in to find a cure, not a chronic treatment regime.

The attempt to do welfare as a "universal" system, with the same rules for everyone, means a bloated bureaucracy enforcing inflexible regulations. If welfare were, say, to be dealt with at the parish level, and the barriers to job creation caused by taxes eradicated, I'll bet you more people would be found some work, appropriate to their abilities, even if it didn't give them everything they need and then people would feel much better about helping them out with the rest - because they were trying to help themselves as best they could. We have no way of measuring that at a national level really.

We have a Professor here at Brookes, a chap called Steven King. His area is the History of Welfare mostly in the 18th and 19th centuries - probably the period which received wisdom says was the harshest environment if you were poor or hapless. But I was fascinated by a lecture he gave a couple of years ago on being elevated to the professoriate (you are elevated to that aren't you?). Apparently when parishes were responsible for pensions, those who actually got a pension - those whom their own peers and neighbours if you like knew had simply tried and been unable to support themselves (in common parlance I guess the "deserving poor") would get on average 75% of the average working wage for their area. For others there were varying levels of support down to a pretty basic safety net that was intended to be subsistence rather than comfortable for those they felt were "swinging the lead".

And then there's the problem of administrative costs. If I had an extra 40% in my pay packet and was going to give it away, I'd know that the people or organizations I was giving it to would get all of my donation. I'll bet for the 40% the state apparatus take off me in taxes, probably half actually gets to someone who needs it, to direct service delivery, if that.

So, given all those disadvantages of, and the singular advantage that people actually vote for, this tax based welfare system at some level or another, is it not just possible that by doing away with all that coercion, all that centralization, all that unproductive bureaucracy, the people who get to keep what they earn would be quite proud to "do the right thing" by their neighbours and communities? If they vote at the ballot box to have money taken off them by the state for things they obviously believe are necessary, would they suddenly feel they were not necessary or that they should not contribute towards those same things without the threats of the state?  Isn't that a totally illogical position?  You'd vote for it but not do it if the people you vote for didn't force you to do it?

And so, at the very least, would it not be at least a courtesy to accept that Libertarianism is an optimistic creed; that it is positive about humanity's innate ability and even need to help each other. You may call that a naive optimism. But I'd rather be a glass half full freedom lover than the glass half empty authoritarian approach that says humanity will not help itself unless it is forced to do so by the agents of a state apparatus that may, just may, cause more problems than it actually solves. Libertarian is not a "devil may care/beggar thy neighbour" philosophy but one that places the utmost faith in people, as individuals, to know and do what is right.

And as to whether it is a "coherent philosophy" or not, I submit that "non-interventionism" is the only truly coherent philosophy in the game. For once you admit the state can do one thing better than we can through voluntary co-operation, you inevitably end up in endless arguments between factions about just how much the state can do better, and the ultimate end of that arms race is totalitarianism - that the state can do everything better than voluntary co-operation. Which is manifestly not true.

...and we still don't seem to know what to do about bankers!

The Bank of Scotland, whatever is now left of it, is 312 years old. That of England just two years older. Ever since the banking system has been built on state protectionism, corporate welfare, monopoly privilege and, at its heart, a gigantic fraud.

The fraud was that a goldsmith could give both you and I receipts for my gold stored in his vaults and make money on both - from me a fee for keeping my gold, from you interest on the receipt you had borrowed from him. Indeed they found they could duplicate this so frequently, fraud upon fraud if you like, that though gold is perhaps regrettably no longer the basis of our money, the "hardest money", real "hard cash", amounts now to just three per cent of our total money supply in terms of everything we all have collectively borrowed and deposited.

To be fair, most goldsmiths at least issued notes of their own. Customers - both depositors and borrowers - chose which goldsmith to bank with on their reputation. If they became overstretched, issued what was felt to be too many receipts for the same gold, their notes would be less desirable in trade, there may even be a "run" when all the receipt holders tried to get their "real" money, the gold, out of the bank, which of course had much less gold than he had issued such receipts for. Nowadays, however, what they create and destroy in their lending business is denominated in the national currency, a currency issued nominally at least, by the state and guaranteed by the state.

This means it is no longer a private affair between a bank and its customers as to whether their business practices jeopardise their customers' savings; it is a problem for us all. We have ceded control of the supply of money issued in our name to private businesses whose main aim is to make profit for themselves and who, in the course of that otherwise noble pursuit, play fast and loose with the very air the entire economic system requires to function. And states protect them, bail them out as seems about to be the case in the US to the tune of almost countless billions, because they have to guarantee the currency they have so little control over.

Regular readers will know I am very fond of a quotation from Josiah Stamp, Liberal politican, Chairman of the Midland Bank in the 1920s and reputedly second wealthiest man in Britain in his lifetime:

"Banking was conceived in iniquity and was born in sin. The Bankers own the earth. Take it away from them, but leave them the power to create deposits, and with the flick of the pen they will create enough deposits to buy it back again.

"However, take it away from them, and all the great fortunes like mine will disappear and they ought to disappear, for this would be a happier and better world to live in. But, if you wish to remain the slaves of Bankers and pay the cost of your own slavery, let them continue to create deposits."

It rather seems to me that with the events of the past few days, we may be "taking the earth away from them" (or, more accurately and nauseatingly, buying it back from them) which they have stolen from us with their inflationary approach to money, but leaving them the power to create those deposits all over again with which, in the next bubble, they will buy it all back again.

Everyone seems to think that money has somehow been pretty constant. The way it works I mean, not whether we call it shillings and guineas or pounds and pence. But the current confidence trick really began with the depression of the 1930s and the work of two extremely wealthy, powerful men in the US who persuaded the government of their day to set up the system that enabled them to create "our" money according to their corporate priorities. The results of John D Rockerfeller and John P Morgan Jnrs' work was the Federal Reserve and the rapid ramping up of fractional reserve banking, and the eventual demise of real solid backing for that currency.

If the current crisis really does turn out to be the "big crunch" at the end of the cycle begun by that 1930s "big bang" we should be ready with policy to replace that fraudulent, anti-competitive, oligarchical system, designed by the very wealthy to keep them that way for little actual productive work with something different. Entirely different. I do not detect any mainstream politicians with the cojones to say so. Our governments and politicians are but eunuchs to the bankers, and the longer that continues, the more the vast majority of us will suffer.

...and is not "liberal" either.

There are often attempts by ministers (Jacqui Smith is mentioned in Sunday's Independent for example about the recent prisoner data loss) to shirk their responsibility for government cock-ups. There are also left wing commentators who crow that these incidents are clear proof that "neo-liberal" policies of "privatising" government functions are evil and should be stopped; that the "free market" does not work in the public sphere.

But I don't consider such contracting out of work as either liberal nor as implying that ministers are no longer responsible for their incompetence. Nor, even, are they truly "privatisation". To me the doctrine that says some things are better done by profit motivated companies (or other, non-government organizations) does not mean merely sub-contracting to a government service level agreement.

Yes, such arrangements may save on costs or similar. But all they are doing is delivering the same policies and procedures designed by government. This is the "corporatisation" of government. It is inherently protectionist - the government grants usually monopolistic contracts to firms, sometimes even, like Capita, that started life as a bunch of civil servants deciding they could do better for themselves by making a profit out of what they do.

No, real privatisation, so called "liberalisation" of government functions, should mean the state divesting themselves completely from interference in that policy area. For example, just because DVLA contracts out its computer systems and administration does not mean the registration and licensing of vehicles and drivers has been "privatised". Not bothering with a DVLA at all and allowing insurance companies to work out ways of ensuring the drivers and vehicles they are prepared to insure comply with what they consider to be safe would be. i.e. a different way of working, free from government entirely, and open to proper competition where new ideas and ways of achieving similar ends can be developed. Finding new structures, free from the dead hand of government to do the things we need, rather than what politicians think we ought to need.

Similarly with ID cards or passports - it is not "privatising" simply to contract out the development and implementation of a government policy to profit making firms. Indeed, this is anathema to true economic liberals - for it is corporate welfare, money for old rope if you like. My idea from yesterday about getting rid of government validated passports entirely and instead letting people buy their own guarantee of identity if and when they need one using a new mechanism such as digital certificates would be liberal; the true privatisation of functions the state previously chose to regulate and deliver itself.

And of course, such liberalisation may not end up being delivered by "for-profit" corporations at all.

So Jacqui, stop trying to hide from your responsibilities. You have cocked up just as surely as if the person with the memory stick were your permanent secretary. You are incompetent. Indeed doubly so - for not only have you failed to do your job, but you've even failed to make sure the simpler option - getting someone else to do it for you is done properly.  You should go.

The Competition Commission has suggested, perhaps commanded (I no longer know what sort of power the CC has given that most competition issues are meant to be dealt with on a Europe-wide basis) that BAA ought to sell some of its airports, and in particular two of the three main London ones. I am uneasy about this for two main reasons...

First off I am deeply suspicious about the timing of the Competition Commission's investigation which seemed to be a (possibly coincidental) reaction to those foreigners (Ferrovial) taking over a British company which had owned those airports for a significant time. If there was a problem with monopoly, surely it should have been taken into account when BAA was first privatised.

And second it is a big step to try and force someone to divest themselves of their own property, especially when it's not as if they are "absentee landlords" but working, and presumably working quite successfully (other than the debt burden) the property.

DeparturesBut there is another problem. The monopoly is not really about the airports themselves - and indeed making them compete directly by being owned by separate owners wanting to maximise their income from each individual airport is likely I would have thought to result in heavier use of all of them, increasing the discomfort for the folk who have to live as neighbours of these smelly, filthy, noisy facilities.

It is exacerbated by the fact that what they really control is access to the airlanes that supply those airports. Airlanes that are, in the economic sense, "land" - part of "unimproved" natural resources with finite space - and in this case also time - (though of course safety technologies can increase the capacity a little) for all the potential users. This is part of the commons, and Ferrovial/BAA and the longer established airlines profit directly from the monopolistic enclosure of those airlanes.

Like the Electromagnetic Spectrum they are part of the "commons" and should be leased at their full economic rent from the state for our collective benefit. They are most commonly called "landing slots" and are worth a huge amount of money - Deloittes reckons that peak day time slots at Heathrow are worth up to £30 million per pair in summer, and there are 9,562 (4,781 pairs - one to land and one to take off on) per week in high season, with an overall limit of 480,000 per year at the moment.

The slot situation is currently, by common consent, pretty chaotic. The government has capped the amount BAA can charge and capped the amount by which it can increase the charge, but 97% of all slots at Heathrow for example are not open to effective competition as they are sold at this capped cost to airlines who have been there the longest, so called "grandfather rights". Heathrow is the only airport in Europe at which there is a significant amount of secondary trading in a "grey" market which is where the £30 million per pair arises. All this profit, the economic rent, goes to the airlines and Deloittes goes on to calculate that BA's slot portfolio may be worth up to £2bn if it were included in its balance sheet as an asset compared with its market capitalisation of around £2.7bn!

The CAA should be auctioning airspace rights to all airports at whatever the market will pay, whilst airports themselves should be responsible for charging the airlines for the use of the "improvements" - the terminal access, ground facilities and so on.

This would force traffic that doesn't actually need to use these massively oversubscribed London airports out to existing regional airports first, often reducing travel times - why travel from Lancaster to London to get a plane if the destination you want is available more cheaply from Manchester - as well as bringing increased economic activity to the areas around those regional airports - airports are a huge draw for international businesses. And unless the overall capacity of slots convenient for travelers' points of origin and destination is actually more than required, would generate a goodly sum for the government in a more market efficient way than say fuel taxes.

I hope we will be having a debate at South Central regional conference on Heathrow's third runway proposals. I believe the rigorous eradicating of this money for nothing monopoly on the part of the airports and airlines through nationwide slot auctions would actually obviate the need for the extra imposition this third runway would cause on teh surrounding areas without affecting overall the competitiveness of Heathrow for flights that really need to use it.

Yesterday in my piece about the Policy Exchange think tank's suggestion that Oxford and Cambridge ought to be allowed to expand to as many as a million homes I mentioned the work "Car Free Cities" by J H Crawford which I came across a decade ago when looking into Oxford's last Local Plan. In it he postulates a city of a million people with a topology and transport system that means that any two addresses anywhere in the city would be no more than 35 minutes apart by foot and rapid transit system.

The city is made up of many districts of about 12,000 population like strings of beads along one of three overlapping rapid transport loops. Every home is less than five minutes walk from open countryside. And whilst the densities within the districts are amongst the highest on earth (similar to Seoul, for example, although nothing is more than three stories in the reference designs) only 20% of the total 100 sq mile (10 by 10) area is developed at all, leaving all the areas between the beads and strings as open countryside or managed parkland or whatever. Overall then the density is not a lot greater than Oxford's current density and less than the average of Greater London as a whole.

OxfordCrawfordSuperimposedSmall.png So, for a bit of fun, I superimposed Crawford's one million population city topology onto the ten by ten mile square centered on the current centre of Oxford. Now sure, a million population is only probably about a third of the million households the Policy Exchange report was ultimately suggesting, but if anyone says to you that it would simply be impossible to imagine a million people in the area between Wheatley and Eynsham, Littlemore and Kidlington, you can say you have seen how, and with no traffic and only 20% of the land developed to boot! It would currently take me over an hour to get from the end of one of these loops to about a third of the way out the adjacent one, incidentally.

Now nobody is suggesting that we do this, least of all me. I'm just demonstrating that it would be possible, indeed whilst making more of the green belt actually because all the space would be accessible in minutes rather than in half an hour in the car, it would reach right into everyone's neighbourhood - with open country no more than 400m from every front door. Fitting such principles into existing cities is of course much more difficult than an academic sitting at a drawing board with a blank sheet of paper. They need not be loops for example but twelve strings with termini at the end of each. It would increase average journey times but not the overall maximum of 35 minutes door to door and could be fitted in along existing radial roads as a series of villages.

Collingham Gardens SW6, some of the densest housing in the UK at 23,000 people per square km.Incidentally, the picture on the right here shows some of the housing in the ward with the highest density in England, at least that I can find - a "middle level super output area" either side of the Cromwell Rd in Kensington & Chelsea.  I notice from Net House Prices that there have been 267 £1m plus residential property transactions in the last eight years in this post code area.  This is getting pretty close to the densities that would be required in a city such as that in Crawford's book.  It's hardly slum clearance stuff is it!
