Despite Greece being very corrupt, and without the nescessary qualifications, the EU more than gladly welcomed them into the euro-zone.
As soon as Greece joined, in januari 2001, Goldman Sachs was called to the scene, to clear up Greece's national balance with secret and dubious constructions, so it would be compliant with EU standards to qualify for being granted additional loans.
It is worth noting that all parties, including the EU financial inspection, were completely ok with this improper business.
Especially the German and French banks grabbed the opportunity to make a LOT of money by selling even more loans to Greece than it had before entering the euro-zone. These same banks, as we have since learned, were 'too big to fail'. The bankers knew this in advance, as we have since learned from public inquiry and parliamentary investigation, yet, they saw no moral objections whatsoever to treat themselves to a free lunch, including large bonus desserts, paid by future taxpayer's money.
That the Greekish elite, that, on behalf of the people, accepted the responsability, and thus is just as guilty, took good care of themselves as well, is also a known fact, proven by a long list of names that has been uncovered by the Greekish parliament, and released into publicity. The same list also showed just how much money was transferred to foreign tax paradises.
All the abovementioned affairs thrived under conservative, and social democrat governments, working under the watchful eye of EU public institutions, and not under the present "incompetent" Syriza government of Tsipras.
Then, the bank crisis arrived, and billions of euros of public money were used to save the banks that were 'too big to fail'. Part of this money, 240 billion was used in Greece. There probably weren't any Greeks that ever saw that money, since it went straight to paying those same German and French banks, that had already enjoyed their free lunch.
Aren't those bankers just as much of a fraud as the corrupt Greekish elite? And why do we still allow tax paradises on European soil?
If the Greekish Szyriza party really deserves to be called "incompetent", I daresay that, scaled to their contribution to the European GNP, their incompetence is not much more than 2% of the total European Incompetence.
