On that, what gives the Authority to print the Currency? Is it a Bond at the people expense in a form of Taxation?
As an example, the US Fed Reserve that is no more federal than FedEx are the ones printing the cash at the people expense in a form of Bonds. Just a big snowball of debt hell. The US has some that nobody has and is the World Reserve Currency. We just pawn off the debt to other nations (Bond Sell). That is why we give cash away to other nations as a form of aids/loans. we do not want that crap on our shores. Hyperinflation will be the result. Some world nations are ditching the USD (De-Dollarization) and if nobody take USDs, so the World Economy goes.
Sadam wanted to ditch the Dollar for Euros, you know the rest of the story, same with Muammar Al Gathafi with the Gold Dinar.
The Russians and the Chinese are buying Gold, why? Easy, is a confidence builder. The USD is held by confidence the US will pay with another Dollar, that is nothing more than a Bank Note. If everybody declines it, will go to the true Intrinsic Value of ZERO. So... the rest of the globe that have USD as a backup Currency will go down, what about the ones pegged by the USD.
