High rents -> Homelessness -> Debilitating mental illness -> drug use -> even worse mental illness.
Nowhere has rents quite as absurd as SF but what you describe has happened to me in London.
Reducing homelessness and ever rising property values are not compatible goals.
It hasnt been going on as long and isnt nearly as bad in Munich as it is in SF but the same problem is there.
A key word is visible. Some places solve the problem by hiding the homeless, chasing them to poor neighborhoods or into shelters, etc. (It's the same solution suburbs and small towns use, in a way: Bus them to the city. Then they criticize cities for the homeless problem.)
It could be a coincidence that SF has an epidemic of mental issues and sky high rents.
(although it seems to have gotten slightly better over the past 5-6 years)
Care to venture a guess how much of that is salaries for government employees in charge of the program? Keep in mind government can only grow in size; never shrink.

> "If the United States still hospitalized its mentally ill at the same rate it did in 1955, its mental health institutions would house almost 1.1 million people any given day. Instead, they house fewer than 50,000 patients," - Michael Shellenberger.
Which is ironic, because if you sit down anywhere outside in SF for an hour, there's a rather high and predictable chance that a person suffering from severe mental illness and/or narcotics abuse will park themselves next to you, begin to scream unintelligible sentences, to hurl insults at the patrons and act in a generally threatening fashion. Everybody will try not to make eye contact or acknowledge their presence in any way, hoping they leave of their own accord in a few minutes. You do the usual dance of pretending that the screams aren't at all distracting to the conversation you're having, while also being barely able to pay attention to anything else, in the off chance you need to dodge something thrown in your general direction. Usually nobody gets hurt, but sometimes you get unlucky and lose the stab lottery. Life goes on.
