I think this is wrong.

Silent Gen and Boomers lived in an unusual boom time that hasn't existed before or since. America was the world's factory and everyone else was out of commission. We had it all, and that'll never happen again. Now we're reverting to the mean, and it'll be okay. We still have great wealth.

Just look to the developing nation algorithm. Our wealth is being spent on bringing up other economies (giving us cheap stuff in exchange). That's not a bad thing.

People aren't having sex (or children) because of Internet, TV, porn, social media, modern work habits, etc. You can't unplug from it.

Furthermore, raising kids used to give you an extra farmhand or house cleaner. Now it gives you an expensive equivalent of a dog. Plenty of folks don't want the trouble.

The drop in European and Japanese birthrates predates the modern internet, does it not?

The massive drop across the globe was in the 70s, in practically every developed country.
