Yeah I buy that to some extent. But according to the studies I've read, the primary driver of homelessness is rising rent, not mental health issues.

The actual materials cost of a house, you can build one for $60k no problem and absolute shit-tons of cheap land near jobs (ex: unemployment extremely low in the Dakotas, cheap land, high demand for homeless-tier labor in the fields in bumfucklandia as ICE deports illegals making farmers desperate for anybody).
