>Cities are expensive because space is constrained (artificially in many cases) and lots of people want to live there.
That has ALWAYS been true, so cannot possibly account for today's prices. The last decade's price increases have been driven by the lack of other perceived safe haven investments. Treasuries/Gilts pay below inflation now. That money found a new home: property in tier one global cities.
>The author makes note of the low "property taxes" in London which is just spurious.
Oh come on. Would high taxes on a house make it a more or less attractive investment?
>A £5m house does not generate 10x the garbage of a £500k house.
THIS is spurious. Irrespective of whether that's true or not (it's not: a £5m house probably takes up more valuable land, which is made valuable by everything surrounding it - transportation, shops, parks, etc.), it still doesn't change the fact that low taxes make property a much more attractive investment.
>It's true that the current state of the global economy has meant that fearful foreigners have brought their money and bought property
It's foreigners who have checked out every other safe investment and seen how pathetically they pay. Seen the interest rate on Gilts?
Some are also (rightly) fearful of their home governments (Russians, Chinese, Arabs), and want to park their money in a country where the government is unlikely to decide to confiscate it one day.
>this tends to be at the very high end of the market which shouldn't be affecting the middle class that he's referring to.
Except:
A) It does affect the middle classes too. Prices filter down. Everybody who was buying at the high end of the market and gets priced out buys something lower down, which prices them out and so on. Land used on expensive properties is not available for the middle classes.
B) It's not just the very high end of the market. London property is being shopped all around the world, from Singapore to Hong Kong to the US as a safe investment for upper middle classes. I could show you a hundred glossy foreign magazines advertising property which is "close" to some tube station on the Piccadilly or Northern line 13-15 stops from the center.
