Most blue metros in the US have a bad combination of high labor costs/low labor availability, high regulatory burden, wealthy conservative inhabitants who oppose construction, and working class people who are convinced that construction is gentrification.

I've been racking my brain trying ti figure out what it looks like for US cities to pull out of the housing crisis, and I think it's either going to take about a generation, or there will be some catastrophic event (Great Depression II, WWIII) that changes the political landscape so drastically that nobody can really oppose housing anymore.
