Homelessness is far from evenly distributed, and the states with the worst drug and mental-health burdens are often not those with the most people sleeping outside. The episode makes the structural case that rent levels and rental vacancy predict a region's homeless population better than poverty, addiction or mental illness, then steelmans the counterarguments.
Structuralists and those stressing behavioral health still differ on emphasis, though separating scale from who falls resolves much of the conflict. How quickly new housing lowers homelessness, and whether counts are accurate, remain debated.
