Roger has the gist of it.
Consider these statistical facts:
Greece currently has 26% unemployment.
23% of the employed work for the government, so they essentially produce nothing.
Pensions for the retired government workers amount to 18% of the GDP.
Greece is running a debt that is twice their Gross Domestic Product figure.
Greek banks, though still primarily solvent, have no ready funds that can be loaned for business expense and development, at any interest rate.has been allowed to reach this point due to bailouts intended to keep them on the Euro and in the Eurozone
Greece's GDP is 25% lower now than 5 years ago.

This is a recipe for collapse. and no finger-pointing at banks or the tax-dodging rich will change it. Greece has been allowed to reach this point due to bailouts intended to keep them on the Euro and in the Eurozone, certainly not due to any corrective measures adopted by Greece. They will hold a vote of the people on July 4 to see if required austerity measures attached to another bailout are acceptable. Based on previous Greek reactions to imposed austerity, and the fact the current prime minister was elected based on promises to reduce austerity, I think it will be voted down. So Greece will leave the Eurozone, and go back to it's traditional Drachma currency. And what value will that have? They will still be insolvent, and where will the bailout then come from? I am guessing China, whose motives for any bailout are pretty frightening to me.
