What we do have (for now) is a currency that is magically perceived to be above all other currencies and is therefore in use as the worlds reserve currency. In reality our currency is fabricated out of thin air just like all other currencies and there are no fundamental differences between them that make ours magically better than the rest. Soon, when the rest of the world doesn't have to convert their own currencies into US Dollars in order to purchase things like oil, we will find out what hardships our massive debt will bring upon us. When the rest of the world doesn't need to play by our financial rules things will get seriously ugly here. That is the goal of all of the international G20 summits. The goal is to sever the world from its fabricated and wholly artificial link to the US Dollar, so the rest of the world can finally function financially and economically on a level playing field with us, and the rest of the world will finally not have to buy our debt (kiss our feet) in order to have US Dollars in hand to spend so they can purchase things via international trade.
