It's really not mostly mental health problems. I've studied this issue for years.
I write about homelessness on Street Life Solutions. I try to write about housing and community development stuff elsewhere, like Eclogiselle.com and https://projectsro.blogspot.com/.
This post wasn't intended to be some opus solving everything. I wanted to make one point: California's extreme homeless problem is not somehow entirely the fault of California government, though that is a factor. There are other factors, like weather and a national shortage of housing that has been ongoing for a lot of years and isn't remotely peculiar to California.
California has 12 percent of the nation's entire population and 27 percent (or more -- different sources vary) of the nation's homeless population. That's not just a "California problem." That's a national problem disproportionately impacting California.
There's a lore more to the issue than can be contained in a single post. I tried to make one point and only one point. Addressing how to resolve the nation's housing problems will take more than a single blog post.
But thank you for commenting.
