The reason is the neoliberal shift. The US used to have more union activity and was more social democratic when it did.

What democracy? Capital is stronger than any democratic system that I know of. But unions etc. provide enough of a counter-weight in some nations.
The US has a particularly bloody labor history according to Chomsky. From memory that was probably in contrast to other advanced nations which happen to have high union participation. In case that’s where you are from.

You will help me understand. With what? Because your FUD “less manufacturing” and “more individualized” BS reasons don’t help explain it.
