Inflation is the loss in purchasing power of a currency unit usually expressed as a general rise in the prices of goods and services. In modern times inflation continues to be blamed on private greed, and governments still seek to restrain it by laws and regulations, sometimes even devaluating their currencies as they do so. The United States has experienced much inflation during the twentieth century, especially since official efforts to maintain the gold price at thirty-five dollars an ounce did not succeed during the presidencies of Lyndon Johnson and Richard Nixon.
