He discusses central banking, New Deal monetary policy, Nixonian fiat money and fixed exchange rates along the way, and provides a blueprint for a return to the reserve gold standard.
Rothbard shows precisely how banks create money out of thin air and how the central bank, backed by government power, allows them to get away with it; he explains how exchange rates and interest rates would work in a true free market. When it comes to describing the end of the gold standard, he names names and calls out all the interest groups involved.
While Rothbard authored many books, this may be the most important. Its basic principles explained that it is impossible to understand modern-day public affairs without understanding money and its destruction.
