Its not a difficult concept. The “market” is not going to build anything that lowers the price. The market is not going to build anything fast enough. The market is absolutely not going to give a flying fuck about building to create communities.
That's stupid, we already tried social housing and it didn't work. The market is the one and only thing that can reverse the situation, and it has done so before too, we just need to put in place the right incentives
