Europe is full of oligarchs, and has less class mobility than the US. The history of Europe is a history of oligarchs throwing peasants at each other.
A middle-class lifestyle when one doesn't have to spend on the military might fool you into thinking that Europe is egalitarian (everybody looks healthy), and looking egalitarian can look like a lack of corruption if your glasses are dirty. Meanwhile, there are families that have been controlling that continent for hundreds of years.
The funny thing about the European rearmament bluff is that any weapons bought by Europe are eventually going to be aimed at other Europeans. It isn't that Europe needs to defend itself from the outside, it's that Europeans need to be protected from each other.
