EURO vs. DOLLAR

Allan Greenspan is predicting that the Euro will replace the dollar as a reserve currency. I saw this coming after spending 4 months in Vienna over a year ago. Americans seem to be living in the past with regard to the U.S.'s economic strength and vitality. The dollar is no longer the currency it was. Once oil countries and China figure this out, the US economy will be in for a serious challenge. I don't see Democrats or Republicans facing this issue.
