This is a "moral hazard" line of thinking that distracts from the underlying fundamentals of the economics here. Even without the corruption, Greece would eventually be in this situation in the EU because of the structural trade imbalance. Nations like Germany, Sweden, Norway, etc, export far more than they import and do no share the profits. The EU has become a giant capital vacuum cleaner from the poorest nations to the wealthiest. Without fundamental changes to this, the EU is doomed. Greece is just a symptom.
