So many many more people coming into the country over the last 20 yers has not contributed to a housing crisis? Where do all those new immigrants live? They put a lot of pressure on the private inventory of housing. And this is a real problem for the poor, the working class and the middle class. It has caused a housing crisses which if immigration is not curtailed can not be solved. I agree that more public housing needs to be built and for that matter more private housing too but new immigration also has to be limmited. By the way those other countries you mentioned also have housing issues..
