AFAIK 11% of the bail-out money went to Greece, 89% went to creditor-banks.
Mostly German banks, that is.
And I say that as a German myself (though I don't live there anymore and as such don't really pay into the "system" much anymore - I'm in a financially much more responsible country now).
The "bailout" was a nice way to help shift that debt from private corporations to the public (=tax-payer) - and look good doing so.
If Greece doesn't want any more "rescue-plans" like this, they actually don't lose much money. But their creditors will stop receiving money from IMF&Co. This amounts to a de-facto "default" and will stop the influx of capital almost completely.
I do believe it's impossible for Greece to pay back the amount of debt they have. Not in a hundred years.
It takes two to tango - when Greece joined the European Monetary Union, apparently "everybody" knew their numbers where cooked from the beginning.
Politicians can't pay back the money but at least an effort should be made to make them accountable in front of history!
