I think this is a simplification of the problem. I don't think (yes I'm one that thinks most are by choice) is a problem can be solved easily if not at all.

The current solution is put a "Twitter" in a bad area and construct new buildings around. So far seems is working.

I can say that people here are the most friendly ever seen so far (I'm european and I traveled a lot Europe, can't say about others places in the us).

So, I fatigue to think that San Franciscans are "bad" and they left most behind.

IMHO part of the problem is an heritage of and old lifestyle (especially with drugs).

What really upset me a bit is that here these people have no social care for their mental issues. Some are quite dangerous and I got really scared few times when I lived in tenderloin.

Not sure I follow. You're calling this a simplification, but your synopsis isn't that much more complex.

Plus, you think that most are by choice. However, you also point out lack of support for mental issues. I personally find this a contradiction – if you've got serious mental issues and no support, then the ability to choose is basically void.

See, they choose to be homeless in San Francisco. They could have chosen to be homeless elsewhere.

Homeless tend to flock to where it's easiest to be homeless. Definitely seen this where I live, over the past 10 years the city has devoted considerable resources to "homelessness" and during the same interval our homeless population has exploded. Used to be able to walk around downtown and never be bothered, now panhandlers are everywhere and even assault and robbery (previously almost unheard of) are more regular.
