Obviously the euro zone is bad, but I think you're overestimating how healthy the dollar zone is. Oil supplies are dwindling, the weapons industry is losing importance, the financial industry is not what it used to be, the car industry is no longer competitive, few major infrastructure projects are being undertaken, IT is one of the few industries that is going strong, but it contributes relatively little. Europe has a healthy, productive economy to back up the euro and it's a threat to the dollar.
