Hmmmm....so Greece can play the EU for a few more months, fall further in the red, and at some point the German banks have to cut them off. Then, Greece declares bankruptcy and is debt free. Tourists come flocking in, no more forever debt to German banks (which only the elite profited from), and maybe a cruise line wants a 99 year lease for its own private island or two. They can stop the invasion from Africa and the Mideast that the EU encourages. They can strengthen their cultural and religious ties to the Orthodox faith.
Where's the downside?
