After reading this article, I’m really curious how you would model all kinds of other reproduction reducing behaviors that have become popular in recent years and how they many generations it will take them to be squeezed out of our culture. Like say taking care of a pet instead of having a kid in Korea.

One plausible explanation is that birth and childhood have become much less dangerous. Before 1900, children with poor genes died; since 1900, children with poor genes survive and have children of their own.

My understanding of high child mortality rates in the past is that it has little to do with genetics, and more to do with infectious diseases and poor hygiene.
