Not to go into personal attacks but reading your comment history explains a lot. "I went to a pretty well regarded private high school in California." You simply don't know what these people are going through. Kicking them out of your sight is not "tough love" and isn't solving anything. You seem very resentful.

Don't you think that your kind of attitude might be part of the problem? Every country has homelessness issues but not every country treat them like a pest.
