I live in downtown chicago where rents are reasonable and skyscrapers for living at everywhere.
Meanwhile, you gotta move heaven and earth to build high density housing in some cities like SF. Even suburbs will fight 4 story apartment buildings. It's not rocket science.
Let the foreigners invest in building more of them. When the crash happens, the locals get to buy them back on the cheap.
What shouldn't happen is foreigners investing in sitting stock as a bank to store funds....zoning laws are like NIMBY on steroids with a long history of racism and classicism.
That's what really is what we should be angry about.
