Of course, modern politicians and their Keynesian enablers despise the gold or silver standard. This is because linking a currency to a precious metal limits the ability of central banks to finance the growth of the welfare-warfare state via the inflation tax. This forces politicians to finance big government much more with direct means of taxation.
Despite the hostility toward gold from modern politicians, gold played a role in US monetary policy for sixty years after the creation of the Federal Reserve. Then, in 1971, as concerns over the US government's increasing deficits led many foreign governments to convert their holdings of US dollars to gold, President Nixon closed the gold window, creating America's first purely fiat currency.
