He has an impossible job - when taxes are not paid, people retire at forty, government jobs pay people even higher salaries because they actually turn up, then any chance of balancing the books is looking like a Greek tragedy.
Please stop repeating things you don't actually know are true. Greeks work hard and don't retire at 40. Their work ethic is not the problem. Not paying taxes is a problem. The amount of pensions paid is also a problem. Individual Greek people are the victim as much as the lenders whose loans are defaulted on (iincluding me, via my country's contributions)
