The chancellor talks about helping people get on the housing ladder, but other than helping them get into more debt he has done very little. He knows which side his bread is buttered.

Conspiracies abound and conspiracy theorists make a good living pandering to our natural suspicions. The vast majority, including those surrounding Marilyn’s and Diana’s deaths, are nonsense. They persist because we find it hard to accept that famous people are subject to the same chance, and often malign, forces as the rest of us.

But that there are out there a fair few I have no doubt. I believe them to be almost a part of the human condition – from the tiny trader, like myself, who might wish for a private arrangement with a fellow trader not to undercut each other to a mighty conglomerate who might wish to do the same. OPEC is a perfect example. It has also to be accepted that the great majority are successful and that, as a result, we never get to hear about them.

I am a natural born sceptic – which perhaps has something to do with being called Thomas – and while I try to maintain an open mind, I have to admit that some theories are outlandish to the point of being funny. A couple which immediately spring to mind are that the pyramids were built by aliens and that the photos of the moon landings were trick photography.

I do, however, believe that the universe is teeming with ETs. With 100,000 galaxies in this universe – and science is starting to believe that there may be many universes – it surely is down to numbers. However rare may be the incidence of all the important factors coming together to make life possible – the so-called Goldilocks Effect – I find it inconceivable, with such numbers, that it only happened once. Furthermore, I believe that when these factors do coalesce, sooner or later, life is the inevitable consequence.

But returning to Earth and our penchant for conspiracies, I believe I have cottoned on to one which may go a long way to explaining why, when there is a clear need for many more houses, it never seems to happen. It is because the politicos are terrified of bringing about a downward spiral in the value of houses. It is not a conspiracy in which a handful of people have got together, but rather an acknowledgement that one’s home is typically his only significant asset.

Meantime, millions languish in rented, overcrowded and often substandard accommodation, desperate to buy their own homes but unable to do so because house price inflation has advanced at three times the rate of general inflation and as a result the deposit required is beyond their reach.

No one can argue against our desperate need to build more houses. Unlike Japan with fewer divorces, a falling birth rate and zero immigration, we are high on all three; people splitting from their partners need separate homes, a rising birth rate requires more houses (down the line), and millions moving to your country will require places to live.

During the recession the construction industry was the hardest hit. Didn’t it strike you as odd that its legions of unemployed were not put to work building this extra accommodation? The 100k houses built last year was less than half of what was required. What would happen if supply at long last rose to meet demand? The iron law of economics says prices would fall. What pushed house prices up to their present level, racing ahead of general inflation at a crazy rate? Easy credit and too many would-be buyers chasing too few houses. The real question is: if all the political parties are agreed on the need for more houses, why doesn’t it happen? After all, builders would set-to with a gusto and buyers would have not just a house but one at a more affordable rate.

Cameron and Osborne promised a relaxation of planning laws in 2010 and pledged to free up more land for development, but this government has so far failed miserably to deliver. Why is this? The answer, I fear, is that present mortgage holders have an interest in not just maintaining prices but contriving to force them up still further. They love a situation in which they are getting richer by doing nothing. Many are making more on their house annually than they are getting paid, with the difference being that living eats into their salary while nothing eats into their unearned capital gains. So just let a politician come along who threatens this nice little arrangement. That greatest of all feel-good factors would disappear down the plughole. To prick that love affair with rising wealth would make them incandescent with rage.

But in many ways crazy house prices might be compared to fools’ gold. Unless you’re going to flee abroad to a cheaper domicile or downsize, which most don’t want to do, then there are no tangible benefits. So how do the politicos keep them happy in this delusional state and excuse themselves from doing their duty to the homeless? First they acquiesce in keeping planning laws fiendishly difficult and listening too much to the ‘not in my back yard’ arguments. Then they waffle on ad nauseam about converting brown field sites. Then they pedal the greatest fiction of all: that our island is in danger of being concreted over.

Next time you fly over our green and pleasant land, look down and see what proportion of our lovely acres remain green. The Office for National Statistics have produced some very interesting figures on this. I invite you to read a BBC News article titled ‘The great myth of urban Britain‘. You will be happily stunned by the stats provided.  It turns out only 2.27% of England’s landscape is built on. Just look out of your airplane window if you’re in any doubt.
