The EU is losing the support of the masses even in the most euro-enthusiastic countries. As an institution in its whole, people feel that the EU is inexorable when it's time to demand new taxes, dismantle the welfare state, or regulate the length of cucumbers, but then is completely
unhelpful, and sometimes harmful, when it's time to solve the problems of the citizens (migration, transportation, environment, defense, foreign policy...) instead of the problems of the banks. Each member state pursues exclusively its own interest with no vision watsoever of the long-term good of the whole continent.
As an EU supporter, I'm afraid that at the next european elections we'll see a triumph of every kind of populism / demagogy / nationalism, left-wing and right-wing, and the people who get elected will work exclusively to suppress the EU from the inside. And I have few arguments against them left. The EU can't carry on by having only the support of the "elite" who can understand the advantages of the common market. They need to conquer back the trust of regular people, or they will disappear.
