If the EU was doing so well, one of their largest member states wouldn’t have left and there wouldn’t be a wave of far-right politics raging all over. Hungary and Poland are quasi-authoritarian regimes now. Economically, EU’s economy size peaked in 2008, so did many of EU member states including some of those who are doing fine like the Netherlands. It’s the furthest thing from doing well.
I’m not against the EU, but you can’t deny that the past decade has been extremely rough especially for Western Europe. The technologies and innovations of the 10s all come from the US (smartphone, internet revolution) while much of Germany doesn’t even have freakin’ 4G TODAY.
Btw, an unemployment rate of close to 15% a decade into the crisis means that the painful recovery has been dragging on for 10 years. That’s hardly something to be proud of. Can you imagine an unemployment rate of 15% in Taiwan now? Even at the height of the crisis it was like 10% at most.
