It got to a point where construction isn't even really providing housing, because the units are unusable for regular people. There's an apartment block of just studios in my neighborhood which are not up to code (too small) but were grandfathered in as construction started before it changed. The change was enacted so that developers would stop making such useless buildings.
China built enough to house its entire population twice over. Didn't help them keep housing affordable just how the price of gold goes up and down despite a steady increase in supply.
We're well past the point where naive supply and demand is effective. There's infinite, induced demand.
