For an alternative economic explanation of what happened, you can read other posts (mine and other) in here. Basically what it has been done is saving, by an indirect route, the Germans and French banks exposed to Greece without improving (worsening actually) the life of the people there.
Consider that, theoretically, the problem to be solved was the public debt and now, many years later, and after forcing the solution on the patient, the debt is the same or worst.
I have to say, that I find totally alien the moral perspective from wich somebody can say something like "they are a bunch of liars" about an entire country.
Who is the liar? the taxi guy in Athens? the children of the school in the corner? the old people that miss the drachma? the young people that had to leave the country?
Never mind where you are from, a little of introspection (and some history reading) will show you how you could be easily any one of them.
