In the United States, social housing is the least popular form of housing and faces the fiercest opposition from NIMBYs. It would also require trillions of tax dollars to do at scale. For this and other reasons, it is a political nonstarter. Yes, developers are profit driven and this a good thing. So are grocery store owners for that matter and that is also a good thing. Since developers (usually) turn a profit, they attract investment dollars, and in turn convert those dollars into new homes. These new homes, especially if built in desirable areas, give wealthier people options to buy, who are now less likely to bid up the price of older homes as they do now.
