> I know many ambitious parents; it’s not an uncommon combination That is a weird statement. Most people eventually have kids, so obviously the average ambitious person has kids. My experience is actually that there is a bias towards more ambition among the childless. Not because of laziness of parents, mind you. But in the decision whether to have kids or not, ambition may play the decisive role, everything else being equal. It goes so far that I have heard otherwise reasonable people resent childless colleagues because of course those workaholics can afford to push overtime while those with kids are pushed into carreer disadvantages, so they say.
