Socialism is balked by physical reality.  Always has been (again, refer to the legacy of Bastiat's writings on the subject of political economics).  The people of Greece, having been for more than half a century feed a constant diet of socialist crap by their politicians, have become addicted to living "at the expense of everybody else," and with regard to the laughable "controls" imposed by the Eurozone concept regarding government debt-to-revenue ratios, their politicians were enabled by the Vampire Squid types at Goldman Sachs to evade the Eurozone "protections" against excessive fiscal irresponsibility with ease (look into the recent phenomenon of MF Global and former Chief Squid Jon Corzine's "disappearance" of his clients' supposedly well-protected funds as exemplary of the many vehicles devised by the banksters to perpetrate the Greek government's duplicities).  

 

The Eurozone was developed and implemented to concert a scheme of fiscal irresponsibility and spread the weight of that "legal counterfeiting" over the whole of Western Europe, the better to enable the implementation of socialism ("government as Santa Claus") by the politicians conniving at that scheme.  By destroying the validity of the exchange media - in particular by preying on the economies of countries whose electorates tended more reliably to keep their predatory politicians in check - the Eurozone spread the "moral risk" of socialist resource wastage throughout the participant nations, better enabling the least responsible electorates and their government thugs (in the PIIGS countries most notably) to squeal their porcine glee and spend, spend, spend! without let or hindrance on whatever popular pork might promise to buy them the most votes.

 

Very popular, very socialist, very destructive of national - and, via the Eurozone - international economies.
