It's unfortunate, but the reality is that having kids and actually caring for them in a way that gives the best chance to turn them into good, undamaged human beings requires a massive amount of attention that would heavily distract from lofty career goals.
If the drive for career success is strong enough, kids will be resented and treated as such. It sucks, and they probably shouldn't have had kids in the first place, but the biological imperative is incredibly difficult to overcome.
