Such people always have a choice of taking a job at a state factory and a room at its dorm plus enough salary to stay poor but fed and housed. If they refuse such option and willingly deny social norms, they're detained, sent to a labor camp, and forced to work there without right to leave, basically a prison. The good ol' socialist way of solving a problem.
If after sobering up during detention or camp they're not able to work for mental reasons and a court agrees with medical picture then they're placed into asylum, often permanently. Either way, people are not afraid letting kids play unsupervised, travel to school on public transit and taking shortcuts through a park during a night.
Americans have this assumption that homeless people are violent. American homeless people respond by being violent, as it's required to defend themselves from the psychotic non-homeless people. For some reason, homeless people in other places aren't violent.
I'm not American but if I would not been 190cm tall white man I would not take such risks, my wife doesn't, and it's always sorry to hear. Broken windows as is.
