There is one underrated aspect of the Greek crisis.
The fat years before the crisis were financed by private credit for the most part.
The crisis has not been caused by some sort of a self-imposed austerity madness. Quite on the contrary. Austerity has been caused by the circumstances. No human effort could have saved Greece from a downfall in 2008 or 2009. Only a fool—or a supra-national organisation—would continue lending to Greece at that time. No other solution but austerity was possible.
