Their citizens spent that cash.
How strange. It takes seconds with Google and you find a hundred newspaper articles all explaining you that all that bailout money never reached any regular greek folks. Most of it went to Greece on paper only, for one legal second, before going back to the banks to cover interest and debt payments.
Yes, Germany will bail them out. But not Greece. Germany is bailing out german banks, just in a more hidden way than before, because our government understands the people would probably not stand a second bank bailout. But this way, the greek are the evil people, not the banks or the government. Win-win.
You can say the banks share some blame there
No, the banks deserve all of the blame and then some. Lending money to someone contains an element of risk. That is the justification for getting interest on the loan. Without risk, there would be no justification for interest rates, for credit ratings, rating agencies, half the financial system would have no purpose.
You can have risk-free investment or you can have profit through interest. The banks decided they want both. They are 100% to blame, because in a proper world, Greece would have defaulted, the banks would have suffered a loss, the people who had decided to give them a loan would have had their performance reviewed and definitely not gotten any bonuses that year, and everyone else would have gone their merry ways.
That the whole thing has put the whole of Europe into a panic, new institutions get created, billions of taxpayer money is lost, half a dozen countries destroy the social systems that it took decades to build - all of that is the direct result of banks deciding to game the system, and the blame is entirely theirs.
