When America sneezes, Europe catches a cold
That famous saying has certainly been true recently, following the credit crunch sparked largely by the US Sub-Prime Market etc and bankruptcies in Wall Street, there's been bankrupt nations in Europe. Iceland went first but Greece, Ireland and Portugal have all failed. All of the latter three have had to be bailed out by their fellow ECB-nations, the EU and the IMF.
When Greece was bailed out it was supposed to have stopped the contagion, it didn't.
Then Ireland was bailed out and it was supposed to have stopped the contagion. It didn't.
Now Portugal is getting bailed out and it's supposed to stop the contagion. It won't.
Now Greece is having to come back for more money.
Italy and Spain are still looking grim.
Traditionally the IMF has always had a European leader. Makes little difference when Europe, the US etc are all strong and the nations being bailed out are typically third world ones. That arrangement is no longer the case though, the doctor is also the patient. IMF funds are being handed over hand-over-fist to keep Europe running.
There is currently a conflict of interest between Europe and the IMF. As the IMF continues to bail out bankrupt nations in the Eurozone, it would be ethically bankrupt to replace DSK with another Eurozone politician.
When the IMF bails out a country normally, they do so with plenty of strings attached. Devaluation is often part of it, though that can't happen due to the Euro. In fact we have a situation where the IMF in its professional capacity is getting down and involved in trying to bailout Europe, ran by a French Socialist with Presidential Ambitions. That is a problem.
Given then catastrophic state Europe has gotten itself into, the next IMF leader should be someone independent. Someone who can dispassionately get involved, make the tough calls. Whether its an American, or Asian or someone else, it should not be someone involved in the Eurozone.
