Bingo! Some one with big enough balls to say the actually and undesirable reality of homelessness on the streets. The richer the city the greater the homelessness, because the homeless like every animal in the world (us included) goes where life is the easiest. And rich cities, have richer populations that then donate more money to homeless people.
In my hometown there are people that quite there jobs to panhandle, because they make more money doing it. It's not common, but it happens and it shows that it's not a simple issue.
FYI mental illness is also common in the homeless population and for them I'm very much in favor of looking at any solution that'll help them have the success they desire in their lives. *Just saying.
