I know life is hard and shit happens, but I refuse to believe that, except for very few edge cases, people who are staring down homelessness just decide to stay in one of the most expensive places in the world and live on the street rather than move somewhere cheaper And find a cheap apartment. It makes absolutely no sense.
I think if you do decide to stay in Los Angeles, when you have no job, no prospects, no family, no money and no place to live, you should be declared as someone who is unable to care for themselves.
