It’s an income issue as well as a cost of living issue.
I have some friends who had a kid a couple years ago. Both work in tech, and have salaries in the 6-figure range, and childcare was going to be so insanely expensive that they were debating whether or not one of them should straight up quit to be a full time parent for a bit, because childcare was going to be more expensive than one of their monthly take home salaries.
And simultaneously, we have politicians wondering why birth rates are plummeting.
