One piece of the puzzle I'm struggling with in all of this is why if housing is so expensive and rents so high are more houses not being built? Surely the incentive is there, what's going wrong?
You need eminent domain from the government to fix this. At this point - it’s complete class warfare and landowners are fucking over many generations.
There are plenty of landowners that want to build. The issue is that NIMBYs have largely captured the city government and zoning restrictions have made new building mostly illegal. We jut need a government that legalizes new construction.
