I think by the time the wealthy realize they're setting themselves up for the local equivalent of the French Revolution it will be a bit late. It's a really bad idea to create a large number of people with absolutely nothing to lose.
If all that fails, they have their underground bunkers on faraway islands and/or backup citizenships.
Agreed and I think this is a result of a naive belief that we humans tend to have that controlling thoughts can control reality. Politicians still live by this belief but eventually reality and lived experience does catch up. By that time all trust is long gone.
People usually change their behavior after some pretty horrific events. So I would predict something like that in future. For both Europe and US too.
The richest of the rich have purchased islands where they can hole up.
The bunkers are in case of nuclear war or serious pandemics. Absolutely worst case last resort scenario, not just "oh I don't care if I end up there"
