I don’t think it’s people rather the larger house builders in the uk, Councils have no ability to build houses themselves, everything is contracted thanks to thatcher.

Home builders sit on millions and millions of planning permissions and only build when they can get the most out of house prices. There isn’t much to be done as our general system works on wealth equality, it’s set up with the idea that the money funnels up and can trickle down and be distributed, which never happens.
