Yep. Birth control made it so women can choose how many times they get pregnant. Pregnancy is not exactly a walk in the park, so it’s no surprise it’s decreasing as birth control increases.

To override this, society needs to make having kids be “cool.” It’s that “simple,” but there’s no real way to coordinate that in society from the top down without being authoritarian.

So it’s a problem that can only be solved by individual change and convincing others one on one that it’s desirable. And people don’t like that.
