It sounds like the point they’re trying to make is that Americans don’t want to have children because things in the USA are getting bad, but if that was the correct explanation then we would expect to see (1) people in countries where it’s worse having even fewer children, which we don’t see, and (2) people in countries where it’s better having more children, which we also don’t see.
It’s annoying to repeatedly read the same completely unsupported explanations for fertility rate declines.
I used to worry about what women would think when they saw my home, but it turned out that none of them ever see it at all so I might as well be true to myself and collect all the My Little Ponies.
