I've never been to these places in California, but aren't places like Oakland and South Central LA filled to the gills with homeless people?
Yes. And it's a big problem. I don't think they can be classed as working class though.
Some of them work. It's just that CA rents and housing values are insane. The federal government fails to take cost of living into consideration.
Frankly, why sign up for government assistance to pay the $2750 per month rent of San Francisco when a much more rational option would be to simply move to a cheaper part of the country?
PBS ran a story of a woman in Chicago who did just that: rather than pay outrageous rents for a rat trap on the South Side, she packed her bags and moved to Wisconsin.
