No, CO is right. Just about every study of rates of deliquency, addiction and welfare dependency shows that even authoritarian, unhappy and horrid parents are better (overall) than single parents. Being bashed and yelled at by an abusive father is very damaging, but most people who suffer like that can move on and rebuild their lives. No so those raised amid instability and a succession of "mother's boyfriends."
Communities where single mothers are the norm become absolute nightmares. There is a level of disadvantage which no amount of money can fix.
This is a crisis in Western civilization and we need to address it - all of us, right across the political spectrum.
You are so wrong I don't even know where to start. Your "studies" are fictions, your statement is padded with the parenthetical use of the conditional term "overall" and your flip dismissal of "people who suffer like that" is clearly based on rank ignorance. In fact, parental abuse is so horrific precisely because trauma experienced as a child from parents destroys fundamental trust. As a result, it escapes even the best efforts of the adult to reach it with almost any therapies and becomes ever more toxic over time, leading to the generational destruction of families. You have absolutely no idea what you are talking about.
