@Daojoan also if Governments took over the "basic, decent housing" market and built millions of new homes AND prohibited foreign "investment" in those properties AND held a lottery for whom could buy those homes AND restricted who was qualified to purchase those homes on the resale market, housing might get closer to being affordable for all. This doesn't rule out a private housing market for those with the means, but their homes would be more affordable as well.
The basics of human existence should not be subject to "market forces".
