Rubbish? Seems you need to do more research. RMB hasn't been pegged since 2006. It has slowly been allowed to float in a narrow margin around a fixed base rate determined with reference to a basket of world currencies. The worlds trades have increasingly been traded in RMB. As for the American dollar economist
Paul Samuelson and others (including, at his death,
Milton Friedman) have maintained that the overseas demand for dollars allows the United States to maintain persistent
trade deficits without causing the value of the currency to depreciate or the flow of trade to readjust. But Samuelson stated in 2005 that at some uncertain future period these pressures would precipitate a run against the U.S. dollar with serious global financial consequences. In other words Americas fall from greatness is unstoppable and will be exponential at this point, as forcing an even spread of depreciation across international trades. And that is only a thin slice of the collapse.
