It has already failed, and is a dead currency walking:
…we’re in an interesting situation. The crisis is crippling the south, but the south has no power to resolve the crisis. The crisis isn’t comfortable for the north but still looks less painful than the solution. So the north, which has the ability to resolve the crisis, doesn’t have the will to do it and the south, which has the will, lacks the ability.
And meanwhile everything in Europe gets worse. As we’ve said before, with the exception of communism itself, the euro has been the biggest economic catastrophe to befall the continent (and the world) since the 1930s. Politicians in Europe thought they were living in a post-historical period in which mistakes didn’t really matter all that much. They were horribly wrong, and the wreck of the euro is blighting lives and embittering spirits on a truly staggering scale.
An “interesting” situation in the same sense as the ancient Chinese curse, “May you live in interesting times.”
