Eventually everyone hits a breakpoint. Pain teaches. For some it takes a lot of pain.
The problem is that Europe has a long history of feast of famine. There is never a stable middle ground. The place has been in perpetual war of some form since history began. Land war, political war, economic war... and the EU served only to form a governmental pressure cooker. It’s gonna blow and when it does, the crap is gonna fly as far from where it was as physics allow. That means dictatorship.
Consider the rise of Hitler/Musolini, French Revolution etc. One extreme to the other.
Please expand on your assertion. How is the rise of Hitler comparable to what is happening in Europe now?
