To know what the future holds for the US Dollar for people outside of the United States, you have to put your eyes and ears on to the source, the origin of the US Dollars, the policy makers and the Fed Central Bank, and see the trend in the making.
Ron Paul, a Rep Congressman, who stood out with his sincere motive to disagree with some of his country's policies, raises the question to the reason for lowering interest rates and its consequential effect on the people of the United States. This deliberation by Feds to lower interest rates and pumping money (which are not hard currency) only leads to depreciate the value of the Dollar.. according to him. The drop in value of the US Dollar makes the cost of living more expensive for the Americans and any other country which trades on the Dollar. Ron gave the example of the rising price of Oil, which had been tripled over the last few months, and the price of Gold. If you compare the Oil and Gold prices, you will see little changes. The US currency was removed from the amount of Gold since the Nixon Presidency.
The ruling party is Republican F.Y.I. of those outside of the US. Ron Paul, a doctor who delivers babies is coined "Rep. Maverick". What he is saying to the Fed Chairman is basic Economics, not some spectacular rhetoric to gain political mileage. This is the signal to the future of the US Dollar at large. The same sentiment is voiced by other prudent investors, such as Jim Rogers.
