Things dont look too rosy for any of the old established western powers, Europe included. All of them will be having trouble with overvalued currencies impeding exports. But in the free currency market people are still buying up the old tried and proven currencies in the hope of finding somewhere stable to put their money.
Unfortunately this overvaluation of western currencies is simply making the countries concerned more uncompetitive and driving them further towards bankruptcy as imports fail and exports increase.
The developing nations are bound to take the lead eventually as far as currency values and balance of trade goes. Its just a natural process of evolution. A redistribution of world wealth as the most productive countries take the lead.
Unfortunately, the worlds present monetary system is tending to lag behind national trends in productivity and so the whole financial system is out of sync with reality at the moment. All the old western powers think they can borrow their way out of debt, but it just doesn't work that way. Well, not for long anyway.
Bottom line is that eventually, all the old developed nations are going to have to take a cut in currency values and individual standards of living to stay afloat.
