Greek society is in crisis on a fundamental level, not just the financial sector. I agree, no matter who's in charge, if the country can't feed itself, and buy stuff it needs (like heating oil), there isn't much choice other than accepting the terms of lenders. I'm not saying the latter haven't put the knife to the bone, exhausting Greece and fueling fascism.
But, there's no reason the Greek gov can't modernize the public sector, fight corruption, etc. But, I also think the people have to rethink their attitude, starting by treating each other better, including respecting the environment and the land they occupy.
If you think that all ills are foreign-borne, then look at they institutions or organizations controlled 100% by Greeks, like EPO, the soccer league, etc...
