Easy - the strong countries break away from the spendthrift Socialst goofbal countries (I am looking at YOU Greece and Spain!) and go back on their own currencies.
I lived in Germany when the Euro currency took over - I knew it would be a disaster. I just didn't think it would happen this quickly.
The primary difference between Greece and Italy is that Italians pay taxes for social welfare programs they cannot afford while Greeks avoid paying taxes for social welfare programs they cannot afford. The common stain is unaffordable social welfare programs.I think the great experiment in Europe with collectivist social welfare programs has caught up with them and the historically economically weak countries of southern Europe are the canaries in the coal mine for the rest of Western Europe.Western Europe is economically uncompetitive globally and the Asian tiger is going to eat their lunch. The US is not far behind as Obama plays catchup to transform the US into a Euro social welfare state.
