Imo, the fix for the housing crisis is for governments to invest in the economies of small towns and cities with lots of land that can be built on or property that is vacant. Everybody wants to live in sf, new york, seattle, etc. because they are where the jobs are and that also attracts culture. If state governments could give grants or tax credits for companies to start or expand out to other parts of states that are under utilized, this could cause people to move to those areas and relieve pressure on the overpopulated areas.
