So, nothing wrong? Okay.
Dan, you're missing the entire context of what you're saying. It's easy to throw around "the US dollar is the global currency" lightly without understanding the reason for that was the Bretton Woods system that followed WWII, when the rest of the world was pretty much in shambles. The US took advantage of that and put itself in a cozy situation, being able to, for example, lend money under it's own rules (ie: you can't ask for your money back, you have to spend it). They also ran an negative balance sheet to pump US dollars to all those countries that needed to rebuild thus creating the dependency and strengthening the position of the dollar as a global currency. Once the US moved to a fiat currency (and the system effectively ended), it only allowed it to move even more money around.
Now, I'm fairly pragmatic, and I have no problem with "to the winner go the spoils". But pretending that the US doesn't have it's economic enemies that would like to see such advantages eroded and potentially replaced is extremely naive.
