General Discussion

I mean, that's not totally unique to women by any stretch, but I think it's definitely more pronounced.

And let's be honest, there's at least a perception that pregnancy is tough on women's figures, so there's a non-insignificant number of women who end up thinking it's more important to their life/prospects to maintain their figure than it is to make babies. Don't mean that in judging way at all, it's just reality.

But yeah, the reasons you speak of are likely much bigger factors. The growing necessity of two-income households being probably the biggest. If the billionaires want EVERYONE to make more babies (no doubt with the goal of "cheaper workers" in the end), they need to stop hoarding every penny they possibly can and accept that they need to help pay for government programs that incentivize the population to have kids.
