A revolution won't build more houses. Lack of supply, due to cost of new building, due to decades of development-hostile government regulations, are what has pushed house prices so high in this country. I can't locate exact figures right now but the percentage of cost of a new-build home that's land has gone up.
As I see it it's a difficult position the country and government has got itself into now. Continue the status quo and it keeps on shafting future generations with short supply overpriced housing. We now expect 35-year-olds to live in one room in a shared house - how long before we expect pensioners to live like that? But if there's a policy shift towards building the houses we need then that will drop the prices and that shafts the current homeowners who took out mortgages to buy at the high price.
