On the other hand I would argue that evolutionary pressure works differently for modern humans in the 20th century and beyond than it did for the majority of human evolution.

Sure uneducated people now often have more kids due to less contraception options/knowledge and as old age insurance. But then again rich people have more kids than middle class because of well more money and everything that comes with it.

In any case all of this is anecdotal and emotion based because there is not much good data on this. Or maybe there is?
