Areas with cheap, plentiful housing have lower homelessness rates, even if they have higher rates of substance abuse. The "slack" in the housing market—spare rooms, empty units—provides a critical, informal safety net for individuals facing life shocks that is missing in expensive cities.

Instead of reacting to crises, the city of Los Angeles uses an AI system to analyze data like ER visits and food assistance use to predict who is at highest risk of homelessness. This allows caseworkers to intervene with support *before* eviction, resulting in an 86% success rate in keeping people housed.

Cities build institutional apparatuses that perpetuate rather than solve homelessness. Individuals enter emergency rooms for brief, inadequate stays for severe conditions like schizophrenia, get discharged without housing, and move to shelters where they face theft or assault. After returning to the street, police clear their encampments, cycling them through temporary facilities without the sustained psychiatric and social support required to stabilize their lives.

To counter resident opposition to homeless shelters, Mayor Matt Mahan proposes a deal: the city will build the site while also enhancing police patrols, creating a no-camping zone, and increasing blight removal, ensuring the neighborhood's quality of life demonstrably improves.

When the most addicted third of the homeless population refuses help, intervention becomes a moral duty. Allowing them to languish on the streets is not protecting civil liberties; it's permitting an endless cycle between emergency rooms, jails, and eventual overdose deaths.

Various organizations, including housing developers and NGOs, receive significant government funding to address homelessness. This can create a financial incentive system where fortunes are made from a problem that is not necessarily being solved effectively.

Pouring more money into homelessness without fixing the underlying incentive structures does not solve the issue. Instead, it funds the bureaucracy around the problem, making it larger and more entrenched, as evidenced by NYC's budget nearly quadrupling while the homeless population grew.

NYC spends more per homeless person than the median household income, yet its homeless population is growing. This suggests that without proper outcome tracking and incentive alignment, massive funding can simply make a social problem more comfortable and entrenched, rather than solving it.

Unlike Northeastern cities forced by harsh winters to legally guarantee shelter beds, California's climate allows for year-round survival outdoors. This lack of an external forcing function meant the state never built the necessary shelter capacity, leading to a high rate of unsheltered homelessness.
