Anecdotally, I’d say money and the world would be the two big things.

People don’t have enough money to raise kids. Americans can’t afford to give birth with hospital bills. Childcare is expensive, but the alternative is no income. People can’t accumulate generational wealth, so there’s nothing to pass on, therefore no need for anyone to pass it to.

Environmental anxiety is real. Why bring kids into a world that’s about to burn?

Maybe one last factor is rebellion. A small sample I feel like chooses not to have kids so as not to perpetuate the system. The billionaires can’t exploit my kids if I don’t have any.

It’ll be total control almost as fast as his total control over Iran.

What’s the clear and present danger for this one again?

Capitalism, corporate greed, and oil cartels.

Capitalism

There are plenty of things God “might have done,” But this sort of thing is neither scientific nor scriptural.
