Yes.
San Francisco spends millions on the homeless every year. They provide shelters that have beds, food, washer & dryer facilities, recreation, telephone access, and human assistance for psychological and medical needs. Not only that, SF runs a vanpool service that picks up homeless and transports them from and to shelters. I've seen the inside of these shelters, they're full of high and nutty homeless. SF also provides free needles and other drug materials so they can continue getting high. Throwing money at the homeless doesn't work.
What works is to clear the streets constantly, tossing out homeless debris, to send the message that they can't just plop down anywhere and impact residents. Move them along and force them to get help and pick themselves up. Otherwise they multiply like the vermin most of them are.
More like billions. Almost a billion (800-900 million) in “official” homeless programs from City Hall, plus police, medical, state, federal and private programs.
And still nothing is better.
Part of the problem is there are a lot of “iron rice bowls” in the politicized bureaucracies and government-grant supported NGOs.
