The EU has been an unmitigated disaster, really.
I disagree. There has been a lot of planning errors, but we are living in the longest period without wars in all of Europe's history. Not to mention that ten Eastern countries have (slowly and grudgingly) accepted to follow democratic rules after a century of different sorts of dictatorships. Boring and elitist as meetings in Brussels may be, political boredom tends to be far better than "excitement" and "revolution". My own country, Spain, had just come from a 40-year fascist dictatorship and had a terrible GDP and absurdly high levels of inflation (like 20% year after year) before joining on and being forced to control those stats to be allowed to join the Eurozone. And the Eurozone is, in fact, saving up millions of euros (or any other currency you want to use :P) in exchange rates and other trade costs.
Are there political issues between countries? Did the crisis show a lot of problems that need to be fixed? Yes, but just look at the other side of the pond. The EU has managed to integrate 28 countries, with different languages, history and traditions, with an amazing degree of success. Considering the US started as 13 almost-identical (identity-wise) colonies of the same country with the same basic law and the same language and history, and needed several decades and a civil war to achieve actual union, the EU has been a resounding miracle by comparison.
And, last but not least, any European country alone -even Germany- is tiny and irrelevant when negotiating anything with the US, China or Japan. Outside of the EU, the UK would struggle to make their voice heard at any level. On the other hand, the EU as a bloc has 500 million people and the largest GDP in the world. The difference is stark.
