Most "economists" and "investment strategists" view the dollar as merely the reserve currency of the world.
It is far more than that.
Every dollar deposited in various banks across the worlds, in addition to its economic uses, also serves as a security deposit. That is, the more dollars a given region has acquired, the more "attention due to significance" (either good or bad) the U.S. Federal Government attaches.
I have mentioned before that the number one export of the U.S. is not anything physical, but "Order".
