It's because their government tried to give their citizens extremely generous benefits that they couldn't afford. Spain, Portugal, and Italy are having serious issues for much the same reason. You say it's the evil banks. No, Greece borrowed huge sums from multinational banks to pay for those benefits and couldn't repay the loans. If it weren't for loan guarantees by the EU that forced austerity measures on Greece it could have started a chain reaction that could've brought down the entire banking system. That's not just rich people money but the savings of millions of average people. But you carry on like a spoiled child and scream when you don't get your way. Much like the Greeks.
