Someone on here had mentioned something I never thought of before, and it might be a cop out I don't know but "quality of life" isn't something for people of authority or higher societal status to figure out for another person. To put it another way, just because a person is living on the street doesn't mean that person doesn't want to live on the street and you, as an individual, shouldn't make such assumptions. They may seem to be in a bad state, but, perhaps, that's their lifestyle. SF is hands-off for that reason.
The services exist in SF for those who want treatment; a homeless person may subsist on the nice weather and any government social services alone if they choose that lifestyle. People go in and get their treatment, food, medicine, blankets, etc. and then they're on their way back to their living area.
Is it right for me to judge them based on their lifestyle? Should the government insist that they're living incorrectly and explain to them that they're messed up in the head and that normal people don't want to live on the streets?
