That's sort of fascinating. I mean is that an absolute or relative thing? If we were all as rich as Bill Gates would we all have more children? Or if we were all as rich as Bill Gates - but Gates in turn was wealthier still - would the number of children we and he had remain the same?

Interesting question, I'd say both. The harder it is to stay in the middle class (by arbitrary standard of living) or "ascend" by incorporating in Ireland, the more hesitant people are regarding children. F.e. if middle class population % is big (like in Czechia or Sweden), there is higher fertility.

In my personal experience the rich have a fairly bimodal distribution. My middle class friends have 1 or 2 kids. Most of my rich friends have 0 or 4+. The big families skew the average.
