Why do I personally care about the homeless issue as much as I do?

I left San Francisco 28 years ago because I felt overwhelmed emotionally by the homeless problem and have been back for about eight years.  I see the situation as just dragging out to infinity while one block from my home is a low income housing project that has caused me no harm at all.  Do I expect anything to change.. eh no.  This can drag on forever.

I saw ten homeless people on two blocks in the center of the tourist area!
