Why is homeless people in the tenderloin so bad? Is there a safety issue? Do they Rob or murder? (Genuinely asking) If not, than why is it so bad? Because you don't like seeing the poor? I mean sure people forced to homelessness is a problem from their view point. This is usually related to their upbringing and could be avoided if you have a strong welfare state that don't let children grow in crappy situations with bad education and poverty, with a sense of security in the future.

When you don't have that, most of the time, you'll grow up and be homeless, or your kids will be.

But the homeless of today are just a symptom of deep rooted problems, throwning money on taking care of them now won't make them disappear.
