In the US at least it starts off with the fact that something like half of all births are totally unplanned for. Then through some combination of hubris and stupidity most Americans don’t actually make any substantial effort to learn how to be a parent. Then between the cost of it all and the general social malaise lead to the parents lashing out at the weakest and most vulnerable people in their vicinity - their children.

Of course our society facilitates this bad parenting. Family planning is extremely inaccessible and sometimes even looked down upon. The same goes for therapy or counseling. Children cost a lot and there’s very little universal support. Still though it’s kinda shocking to me that people don’t take it upon themselves to make an effort to learn and plan. Anecdotally it seems that millennials and Gen z are more inclined to that though which is good.
