It is not only a big issue in economic professional circles. The mass media, too, puts the competition between the euro and the dollar as the key currency of this century on the front pages.
Meanwhile economists still dispute possible outcomes , I found some promissing indiactors on the question which currency will make the race. For example, top model Gisele Bündchen now only accepts her pays to be invoiced in euro. Similarly, rapper Jay-Z in a recent movie clip rambles with euro notes rather than with dollar bills. Wow, this is how changes in public mindes slowly evolves!
