I believed this when I lived in California. Now I’m not so sure: it is true that people without shelter can easily die in much of the country, but California isn’t the only place with mild winters. Why don’t Arizona, New Mexico, large parts of Texas, Georgia, Florida, Alabama, etc. have the same problem?
Assuming that California will just naturally have a larger homeless population than everywhere else means that nobody will spend much effort trying to solve the problem. Is it possible that California is just unusually bad when it comes to handling homelessness?
