No, it's just the fact that some part (not all of it) of the economy has become zero sum, primarily low skill labor. When people get screwed in a zero sum game they want someone else to get screwed instead.

It's not surprising. It's completely obvious.

The thing is, in Germany the people voting for the far-right party are actually doing fine economically and so are their friends.

I do agree that parts of the economy are not working properly. And still we can't seem to get ourselves to vote for different politicians that might do something about it. Yeah that means stuff changes and change and new things are scary, but not fixing those things would be worse.
