We had the same verbal diarrhea and scare tactics a couple of years ago. Same country too. Seems to me it was a non-event then and I can't see why the world economy would collapse because Greece can't (or won't) pay their bills. The loans will be restructured, Greece won't pay again and it will start all over in another few years like it never happened before.

It's like giving your wife money and thinking you are going to get it back. Or vice versa.....

If you're stupid enough to front someone a ton of money (actually, it's more than a ton) with no collateral then who's fault is it really?
