Yes, it's that way all over the country. My own town last week or so ran all the homeless out of their tent city that upset so many of the public that drove past it at 50 miles per hour, though I never heard of any of them donating a lot to help the homeless. A local church is getting a lot of flack from neighbors for allowing a tent city on their property.
They may be fresh out of a job and home, they may be and probably are drug addicts, they may be sex offenders, they may be mentally ill, they may be military who saw such horrors that their minds snapped, but in the long run they are just human beings. We do have two or more shelters, one does not allow dogs, which are their only friends and I think it's decent of them to choose their friend over relative comfort.
I don't have an answer, neither does anyone else.
