As a nation it is in our own interest to liberate ourselves from the vice and entrapment of the valueless US Dollar backed only by the bullying might of the US Federal Government. To beholden unto the US Dollar is to be trapped in an inflationary abyss as the US Federal Government just print and print and print dollars and float them as currency. They make their fake currency current by the threat and use of violence and weapons of mass destruction.
US President Nixon acted in his national interest when he pulled US out of the Gold Standard. We therefore lend currency to the US Dollar when we us it as our medium of both external and internal trade. The US Dollar is a fraud engineered by the Federal Gangster Government run by cartels of vested interest.
