And I don't see that changing. Due to a combination between structural issues, different interests between North, West, East and South and the crisis-related rise of right-wing populism across many European countries (to various degrees, not every country has turned into Hungary), it's getting worse. And I don't see what's going to change that.
I used to be in favour of an EU "federal state". Now, I'm not so sure. Political union makes sense for countries with similar culture and economic interests. But as it is, I see regional blocks, not political Europe. Maybe dropping the common currency and splitting the EU into "mini-EUs" would be a better approach?
