There are undoubtably people who are still doing okay in Greece, and there may even be some whose fortunes have advanced in recent months. Those people would be those who recognised the flaws in their own society and took measures to hedge against the collective folly going on around them. This is hardly a new phenomenon in history.
So wait a second, there is some specific way EVERYTHING was done in Greece, by EVERYONE that f***ed everything up? (of course, minus these few people who recognized the flaws of this way to do things).
This blanket idea is so easily to deconstruct that its not worth doing.
Things are more complicated than this. if you think you can explain an economic meltdown in a sentence or even a paragraph, you are clearly missing the real picture.
