Another thought Dave,
100 years ago you might have wanted or needed to have kids for the economic benefit.Children and adult children sustained the older generations economically with labor, shared income and geriatric care, all at the familial level.
I know that currently in the most developed countries, besides being bundles of joy, kids are mostly an economic liability, but it hasn’t always been that way. Even though it would probably be true that professionals such as yourself historically did not need children for support, it could be much harder to skip out.
