Here is the chart from the Federal Reserve Bank of St Louis showing the exponential growth of the price of gold from 1968 to 2013. Notice the rise of gold price from 1971 – the year of the Nixon Shock. The current fiat monetary system we are on sees the need to have more units of currency (e.g. USD) to buy the same 1 ounce of gold. The purchasing power of fiat currencies like the USD are consistently falling.
