When the population of a city suddenly jumps, increasing density is the ONLY answer. Without extra housing, where do you think all those extra people will live? In the apartments of current residents of course. This is not a view held solely by freemarket enthusiast or "neoliberals" or whatever. Even the DSA understands this. Their only disagreement is that they think the government should be the ones building the housing. I can't get my head around the prevalence of this anti-density view. It's the climate denialism of the left.
