Those cities are mismanaged as all hell.
In my city the city council passes taxes on home builders to include “affordable” units. The homeless tax drives up the cost of new housing and the value of existing homes. Thousands of low income people put their names into a lottery and maybe 20 or 30 of them win the lottery to move into an apartment for below market rent.
I think that a lot of the homeless people in Southern California have been encouraged to move here from other parts of the country.
They will never figure out how to correct it and get things moving in the right direction.
