I'd like to advertise deregulating housing construction as a very clear way to help solve desperate housing problems in many countries (such as in the USA). You can check out more about it here https://www.econlib.org/build-baby-build-now-under-construct...
hint: its not the fiscal conservatives, billionaires or private equity firms.
Those guys will say, "Hey, thanks for getting these poor folk to vote against their interest. We'll take it from here and proceed to build the luxury buildings that were too annoying to build before instead of those unseemly affordable housing projects."
