Greece - is workers' revolution, exit from the Euro and exit from the EU superstate the only solution?

There's probably nothing stopping the Greeks from leaving the EU. That only means they will go back to just being " Greece " and more than likely not use the Euro as currency and return to their former currency. This won't absolve them from their debts however, They'll still be in the same boat no matter what they do. BTW the last time I was in Athens, the pollution was just horrible, and I doubt that it's improved any.
