You seem to pretend that Greece is a single atomic unit. The people cooking those books were neither the voters nor the current government, both of whom are victims of the mismanagement of previous governments.

Of course the voters should never have elected them in the first place, but look at the loons that American voters keep voting for. And the Greek crooks were given both the means and the motive to cook the books, because there was status attached to joining the euro, and the rules were not being enforced so strictly back then. And the easy loans after joining the euro let them pretend to their voters that all was fine.
