We enjoy a scale, and present status as the world's reserve currency, that temporarily hides the egregiousness of the Fed's money creation in contrast with Weimar Germany. But we also have a new Fed Governor, and potentional chairman, named Bernanke who has made it public to the world they feel they can crank up the printing press whenever they see fit. That's not comforting if you have savings in dollars.
As Yogi Berra would say, the dollar is so popular, nobody uses it anymore.
