Supposedly there are 40,000-70,000+ homeless in LA, depending on city or county level. Are you sure that none of them should be counted as unemployed?
And the jobs are probably stealing catalytic converters, stripping copper from light poles, etc.
The homeless in California are on drugs and mentally ill. If they’re not, there are plenty of programs to support them, but if you’re on drugs then yeah you’re never gonna afford rent here… you can’t afford to be a junkie and afford rent on an apartment.
