orathic, I could agree. It's almost irrelevent whether the exporters or the importers stay in the eurozone, but both can't. Germany's exit would be a solution probably, but that's the ast thing germans want.
With their huge export without deflation makes them a hell lot of money, and with propping up piigs it's still worth it for them I guess.
About austerity/stimulation. I don't think either is good, sometimes you need austerity, sometimes you need stimulation. Like lower banking and communication costs, public transport while you can tax fossil fuels, alcohol, etc. which has smaller contribution to the economy.
All in all, I don't think there's a general medicine, it should be done country by country, but the breakup of the eurozone is imminent I'm sure. The question is, in 1 year, or in 5 years. After, we might be on the right path.
