Gray, you have no idea of what you are talking about. Let me educate you on a basic level: all those governments you have listed are trapped in a monetary system that refuses to do what it should do to ameliorate their economic woes. Instead, what they have to do is to incur on extremely problematic and politically suicidal constant wage cuts in every single public sector, which then drives the consumption and tax revenues down, and thus worsening their debt status.
Portugal, the country you didn't list, is doing "apparently" what these folks have decided is the medicine. And what are the results of draconian spending cuts? A deficit of more than 10% this year and an economy tanking 4% a year. Of course no one wants to leave the euro *right now*, that would be one step towards the precipice, but staying isn't better.
This idea that these countries are "benefitting" from remaining in the eurozone is something that no longer *anyone* believes, except for some distracted folks out there.
