Wasn't the problem of countries like Greece and Italy corruption?
That seems to be very stupid "mistake" from some very important economists.
Also, having to reign in a double-digit deficit by cutiting the state's chronic overspending also lowered the GDP that was kept artificially high by injecting into the greek economy all that borrowed cash.
So, it's disgenuous to insinuate that Greece's bailout program caused any problem when you're actually referring to the natural consequences of:
1) finding out the true extent of Greece's overspending by fixing their accounting incoherences
2) the impossibility of continuing overspending well over 10% of the nation's GDP.
The corruption narrative is just a diversion from the fact that the whole Euro concept was a bad idea to begin with.
