Where the hell are these people supposed to go? Shelters don't let you stay there indefinitely. No one wants to give them the homes they can't afford or the mental health care they desperately need. Sorry, they're not just going to lay down in the middle of the street and die because that's not how anything works, so what exactly do the cities expect them to do?
My wife is a library administrator and they are working on putting up a library branch in a poorer part of town, and people came to the board meeting to object, because it would attract more of "them" to the area. As if there weren't plenty of homeless people there already.
