This is very counter to reality . In high income societies ppl who have kids are often the ones the without good access to childcare and education. People have less kids as you move up the income spectrum.
Prerequisite to having kids is removing choice and meaning in life.
"Good access to education" means more time spent in formal schooling, and later marriage. This alone accounts for most of the decrease in fertility; even if the probability of having children per year between two groups is constant, if one group marries at 25 on average and the other at 35, the first group will be 3x more likely to have children (since it has 15 years until 40, the rough end of fertility, while the other has just 5 years until 40).

Unless I am grossly misunderstanding you, this is exactly backwards. Having kids was the most important choice and the most meaningful one I've ever made.
The fact that being highly educated and well-off has made this a somewhat less "obvious" choice is the sad part.
