Affordable housing, as an essential need, should not be subject to the whims of "the market", nor should its construction depend on speaking sweet-nothings into the ears of inherently untrustworthy and predatory private developers.

In a state, hell, in a country with its priorities straight, government would mastermind the building of such housing all over the place, have its upkeep be well-funded—and remove the social stigma associated with it (which, as with so many things, has its roots in racism). People wouldn't have to rely on capitalist entities whose goals are directly in opposition to the public good.
