I find all the economic anxiety in the European Union (EU) to be rather worrisome, from a long-term historical perspective. I think the last 500 years of history demonstrate pretty convincingly that the most benign possible way for European states to spend their time is arguing over agricultural subsidies and cheese standards. It’s definitely a lot more congenial than building tanks and smashing through Poland and Belgium over and over.
As such, I rather hope the EU is able to sort things out and set up systems that prevent these problems in the future. There definitely need to be ways in which the actions of less responsible governments can be prevented from requiring frequent bailouts from more responsible governments, but I don’t think the risk of that happening from time to time is so severe that it is worth derailing the whole European project over.
