I doubt this will ever see the light of day. The European Union cannot get all it’s members to accept the Euro, and the Euro may not survive this recession. Indeed, the German public really wants the Deutsche Mark back and much of the southern EU is suffering under policies designed to keep the Germans happy, which means they might bolt. When the dam breaks, the Euro will collapse rapidly.
Even if they were to try it, there would be no chance of the US signing on to it. It would be less popular than the metric system... The dollar isn’t going anywhere, and neither is the Pound, the Yen, etc...
With the dollar in such decline, suppose China converts to a gold standard ...we’d be toast. They own so much of us now.
Obama is signing us up in final contracts phase as I type this.
