I guess we all agree that Greece has had incompetent political leaders for many years (just like today), but if Greece is a democracy, and it's been one for quite a few years, the people somehow, should be responsible.
While I would like to agree with you on this (there certainly is a lot of corruption and tax evasion there), I think we all know that's not really how things work; under most circumstances, the general public has little or no knowledge of, or influence in, the way countries are run. Further, as bryant.coleman pointed out, the people are being held responsible, in a way: their standard of living has plummeted - they are suffering quite a lot (and have been for several years now).
IMO Greece is falling in debt hole and never gonna pay off! The lenders haven't realized their mistakes yet! They won't be able to give out unending loans!
Of course they realize Greece will never be able to pay back at this rate; the IMF, for example, pretty much said so by itself. Unfortunately, that doesn't mean they are ready to change their extreme neo-liberal commitments - something that will hopefully begin to change once Podemos wins in Spain later this year / early next year (the most likely outcome of the elections).
