I would argue that the evolutionary pressure only applies to a limited level of understanding of the physical world. Think how many kids people like Stephen Hawkings have and how many poorly educated people have.
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?
Do they? I am pretty sure that the vast majority of the human population is poor and not just "I can't afford an iPhone poor" but "I have no food on the table" poverty. The rich are but a tiny minority. In terms of reproduction, poor people win easily. Last time I check, rich people are more likely to be highly educated compare to anyone else and education is a predictor of reproduction rate (more education and less reproduction and less education and more reproduction).
