Housing demand has risen so out of proportion because we have, aside from France, one of the most highly centralised state's in Europe.
Simple as.
Simplistic bollocks of the usual order of your thinking.
The reason why demand is so far out of proportion with supply is a direct result of a set of policies put in place during the second Thatcher government, which have never been rescinded or re-legislated because of their political convenience and economic and financial benefits. The effects of those policies continue to play out.
1) The re-jigged "Right to Buy" legislation itself (the original Labour version only covering voids "in significant need of repair/modernisation".
2) The secondary legislation in 1984 that prevented local authorities from building replacement housing, and instead vested all development of social housing in Housing Associations, funded through the quango known as "The Housing Corporation", a move that has meant that in no year since 1984 has development of social housing matched need. In some years it didn't even match the year-on-year increase in need.
3) The legislating of disposal of local authority landholdings (aka "landbanks") to private developers at less-than-market prices. This move set in motion the preference for greenfield development over brownfield that is still playing itself out on green spaces around the country
All those policies have had direct knock-on effects on supply that have almost
nothing to do with degree of centralisation (unless you're claiming that legislating on a national scale is "centralisation"), and
everything to do with ongoing shoring-up of bubble pricing through limiting of supply. That's "the market", in all it's cartelised glory, working its' "magic", lining the same pockets as usual.
Who really wants to contemplate living in Birmingham ffs, even if that was on the cards?
Birmingham, really?
WTF is wrong with Brum?
The snobbery in u75 lives next door to the gentrification of Brixton. To deny otherwise is ludicrous.
The only snobbery I can see is yours.
