City Journal has an article dealing with the homeless problem, its headline is misleadingly limited to Georgia while the article talks about policies across the nation. The author sees some movement in a positive direction happening, in Georgia to be sure but elsewhere as well, predominantly in red states with Republican governors and legislatures.
It also does a good job of creating awareness of what it ironically calls the Homeless Industrial Complex, made up of people who make their living providing support for the homeless. Paradoxically, more homeless people is what keeps this group funded, so they have no incentive to reduce or eliminate homelessness.
