I've heard of this tremendous wealth supposedly being a major international currency brings the US, but it isn't clear to me how this is supposed to work. Somehow the mere fact oil prices are rendered in dollars makes the US richer? If this is true and the sums as vast as indicated, there is an advantage to being a leading currency. If the Euro is to assume that role, the EU would get that wealth instead and I'm at a loss to see how this would be fairer.

The Euro recently has depreciated, so countries leaping at the opportunity of using Euros rather than dollars in their international transactions would be feeling that loss in value when purchasing from the US. If instead they stuck with the dollar, whose value is climbing with respect to most of the world's currencies, then they'd be finding the same volume of exports buys them more Euros than before.
