Quote from eusdaiki:
It doesn't really matter if the USD is a global reserve currency, it is a fiat currency and so it is subject to inflationary risks just like any other fiat currency. Your argument would be valid only if the value of the USD was based [fixed] on the value of those commodities [in someway similar to the gold standard] ...
As long as you have a fiat currency the FED can devaluate it as it pleases, and it fact they do it every day. With every time a new emission coming out of the FED every dollar is worth a little less. Since the newly emitted dollars are not backed by any asset but they are rather a counterfeit.
Today the USD is worth less than 1/20th of its 1950 value. Back then $35 USD = one ounce of gold... today, well... check the charts...
