Re: I don't much care...
"And that's not accounting for birth rate or increased longevity."
The single driving force beyond all others that accounts for housing demand is the size of households - down from 5-7 per housing unit in the 1950s to less than half that now.
Even if no immigration had occurred there would be a critical housing shortage now, simply due to this seemingly simple change in population demographics.
The UK government funded councils to build a lot of social housing in the 1960s-70s for 1-2 person households, intending it to be retirement housing for pensioners. It was _all_ taken by young couples, and then the thatcherite selloffs happened (taking an old labour idea but selling at 90% discount AND prohibiting councils from using sales income to build more housing - it was a calculated way of nobbling labour dominated councils by converting housebuyers to conservative voters (blatent vote buying) and simultaneously fomenting discontent by ensuring the councils couldn't house new tenants). Those selloffs ensured that older folk in 3-4 bedroom council flats had nowhere smaller to move into and simultaneously ensured that couples in 1-bedroom flats had no place larger to move into.
The whole EU referendum is a dog-and-pony sideshow, intended to distract from the simultaneous trainwrecks of NHS, welfare and education system disembowellment, the pensions system falling apart (there simply isn't enough money to pay for retiring Boomers) and the housing crisis pigeons released by Thatcher coming home to roost. It's working exactly as planned too.
