It's a fantasy. People in Germany seem to ascribe cultural or moral attributes to the people that cause this problem without once understanding the circumstances. Crises reinforce bad behaviors. The answer to the national schism was repression. The answer to German occupation was a political war. The answer to starvation was food imports in exchange for a military build-up and vassal-dom which evolved into the curtailment of civil rights and totalitarianism. The answer to fascism was then a ban on political prisoners which fostered corruption. Round and round it goes, where it stops, nobody knows.

In the interwar period, Germans behaved much the same as Greeks, proving once again that circumstances drive behavior.

Despite what people think, the current crisis makes Greek tax-dodging not only logical, but an absolute requirement.
