As an American, I could have written Russ's comments. He said exactly what I've thought and said for years. The EU should have stopped at trade agreements like NAFTA as each country still keeps its sovereignty. The EU is doomed even if Brexit is not accomplished now. Nationalism and patriotism are too powerful a force as the major entertainments of the twentieth century had proven. Not to say this must end in conflict. Just that everyone is happier flying their own flag.
I don't agree with this view of things. In fact I think it is the exact opposite.
The over reliance of Europe on trade as the core integration factor is the very cause of the current failure of Europe to convince its citizens.
In case you have not realized this, education, when designed to do so, can change the way people see things accross generations. And it has in some countries. There is nothing intrisinc about people with different cultural backgrouds unable to live together. And this is exactly why I quoted "education" as a key failure factor under lying the Brexit.
In case you have not realized this either, a large majority of citizens in Europe consider that policy makers in Europe have built a Europe designed to help large corporations in which they recogize themselves less every day that passes by. The Europe of the citizen is in favor of free enterprise (this isn't about "socialism"), but it is strongly opposed to the influence of capital on state, and Europe is seen today as have enabled just that.
This also what people mean when they say that Europe isn't democratic. This isn't just about the lack of direct relationship between people and their EU level representatives, it is a lot more about the perceived focus on large scale lobbies and lack of support for small scale initiative.
Obviously, some extreme right parties, such as the Front National in France, are trying to turn this into a preference for one's own Nation, but they are far from representing the dominent thought process.
