It's not that easy. Germany's social security system for instance provides all of that yet still there are homeless people in Germany. Probably on average not as many as in San Francisco but still noticeable.

I'm no expert on that matter but I suppose the causes of becoming homeless are too diverse for the problem to be solved easily and not all of these causes can be attributed to society. Debt, drug addiction, mental health issues to name but a few.

Germanys social security system is effectively flawed, as it can decide to give people no money at all and thereby produces homeless people. Even without drugs and big debts and mental health issues, if you lose your job and got bad luck with the person working on your case, it is way too easy to become homeless. Even in Germany.

All of these other variables you mention can be prevented by having a good mental health.

In a lot of places in Europe, people CAN get a therapy with a shrink (b/c or when it's covered by insurance), but they won't because of retarded cultural stigma.

In the US, it's pretty much the opposite situation.
