We went to SF in 1990. Saw homeless ppl EVERYWHERE! Most were obviously oblivious to ppl and surroundings. Talking to themselves very animated. Arguing with selves, waving arms around in air. Nothing has been done in all these years about the problem. I know a beautiful young boy who grew up to be a homeless SF Meth addict. His wife and 2 kids left him last year. Last we heard he’s living in his mini van. Won’t start or run. So sad but no one can reach him. They all tried.
