Nixon’s decision in 1971 to withdraw the United States from the gold 
standard greatly influenced the future direction of humanity. The US 
dollar rose in importance from the 
mid-1950s to become the world reserve currency as a result of the need 
for countries to use the dollar in trade. One of the most consumed 
commodities in the world is oil, and as is well known, the price is set 
by OPEC in US dollars, with this organization being strongly influenced 
by Saudi Arabia.
