I think the moral is that if your country is run by a government that just wants to win votes at each election, they will do what the public want, which is not likely to be what the country needs.
Their and our governments have allowed a debt fuelled boom to turn to bust. None of us moaned about the credit, civil service pensions, schools, hospitals etc when debt looked like it was going to be paid off by growth. In turn fuelled by more consumer spending.
It didnt add up then and it wont add up now. So sadly the same governements are using the same tools that caused the problem to try to fix the problem.
It wont work, tax payers for decades will pay for the mess. Greece will go bust and take its lenders with it in the end.
