I think homelessness is one sign of cultural collapse with the loss of family structure in a lot of cases. You have absentee fathers resulting in no role model to look up to and to straighten your ass out when needed and to teach personal responsibility. It sends a lot of young people adrift trying to find the way themselves but end up with drugs and the wrong crowd. Soon it's a life style. It's not the government's responsibility and it doesn't take a village. A possible avenue of improvement in my mind is to re-introduce the military draft and give some a foundation in discipline and an ordered life before they get too far out of hand.
