> do something again the blatant corruption, burocratie and tax evasion
Corruption and tax evasion are an economic problem, not a moral one. People decide whether or not to pay taxes based on many factors - convenience, value, habit, punishment, etc... In a 'developing' economy, like Greece, if there's a history of not paying taxes, you need to provide incentive to pay taxes. Because if you all of a sudden raise taxes and enforce it hard, you don't get tax evasion - you get capital flight, which is much, much worse for the economy. And it's all too easy to move around in the Eurozone.

Greece did not spend other EU citizen's money. They sold bonds at the market rate to banks and investors that BOUGHT them, and their debt spending was entirely sustainable up to the financial crisis (not sure if you've heard about it) which rocked the whole world. The troika bailed out those banks, with the vast majority of the "EU citizens' money" going to those banks and only a fraction of this money ever made its way to Greece.

You know what hinders startups, business, and innovative people? A repressive tax regime. Like the one the troika imposed on Greece...
