Ideally, support from society would stop them from going feral. There's no reason we have to be insecure in housing (there are more vacant homes than homeless people), no reason we couldn't have universal healthcare in the USA (plenty of other countries have it), no reason the economy has to have a ceiling on unskilled labor (during my parent's generation a factory worker could support a family).

Instead, we prefer to live in a ruthless society where losing your job puts your very survival in jeopardy. The problem is capitalism, not the biology of men.
