in "due time" would probably be thousands of years, if we're assuming natural selection is the main drive of family lines ending in modern society. but the first world is a society where fucked up parenting is highly valued, it's important to our overlords that a bunch of poor, broken, desperate people are churned out so they can exploit them for as cheap and easily as possible. healthcare & education is mostly either inaccessible or extremely hard to get (even in many places with advanced universal or free healthcare, it can be a challenge to get proper treatment for something that's not an immediate visible threat to your life). this is especially a problem in countries that aren't european. so we will keep having a large portion of familes consist mostly of dysfunctional parenting, for as long as corporatism can sustain.
