The only countries I would understand for wanting out of EU are Holland and Germany. Then again look at the common values in between - aka Deutsche Bank...APGs monster kids are all Deutsche Controlled and so it goes.
Financially Germany is setting the tone and if one makes a difference between fiscal and economical balance, one would understand they are doing great. Greece, Spain, Italy are never going to be economical powers, due to climate mostly. They are never going to be financial powers either and Greece was bombarded financially by US banks not long ago, killing the entire region's investments effectively. Credit swaps, anyone?
