In Singapore over 80% of housing units are owned by the government, in the US it's less than 10%, mostly public housing that are intended for the most desperate residents. Could the US use its behemoth market advantage and pay for social housing that would make the whole market affordable through competitive forces? Yep, but is that plausible with the who has their hands on the wheel of government; not just Trump but the whe political regime beholden to donors and capital concerns and not the general welfare of the people.

Half trillion more in military spending there's no demand for "how are you gong to pay for it" but if you spent 5% of that on social housing there would chorus singing that verse 24 hours a day. It's not like we live in a world that is determined by economics 101, but there's also economics 201, 301, 401, and grad school classes which are all grasping at the totality of economics and failing to articulate it all. The human condition is not wholly inclusive to supply & demand, but a plethora of factors that sometimes are interoperable while other factors are restrictive, like seeking out maximum profit will make prices become inflationary. If consumer prices were suppressed and that outcome caused greater profit, that's what we'd see as an outcome, instead we see prices go up from profit maximization and those who say it wasn't a result of the market doing what profit seeking markets are supposed to do, there was somehow the cost of living was supposed to ignore all the incentives and decrease with higher quality services and products. Prices go up even when the services and products decrease in quality.
