Long Depression
Nobel laureate economist Milton Friedman, author of "A Monetary History of the United States", on the other hand, blamed this prolonged economic crisis on the imposition of a new gold standard, part of which he referred to by its traditional name, The Crime of 1873. This forced shift into a currency whose supply was limited by nature, unable to expand with demand, caused a series of economic and monetary contractions that plagued the entire period of the Long Depression. Murray Rothbard, in his book "History of Money and Banking of the United States", argues that the long depression was only a misunderstood recession since real wages and production were actually increasing throughout the period. Like Friedman, he attributes falling prices to the resumption of a deflationary gold standard in the U.S. after the Civil War.
Economy of the United States
The United States has been the world's largest national economy in terms of GDP since at least the 1920s. For many years following the Great Depression of the 1930s, when danger of recession appeared most serious, the government strengthened the economy by spending heavily itself or cutting taxes so that consumers would spend more, and by fostering rapid growth in the money supply, which also encouraged more spending. Ideas about the best tools for stabilizing the economy changed substantially between the 1930s and the 1980s. From the New Deal era that began in 1933, to the Great Society initiatives of the 1960s, national policy makers relied principally on fiscal policy to influence the economy.
During the world wars of the twentieth century, the United States fared better than the rest of the combatants because none of the First World War and relatively little of the Second World War was fought on American territory (and none on the then 48 states). Yet, even in the United States, the wars meant sacrifice. During the peak of Second World War activity, nearly 40 percent of U.S. GDP was devoted to war production. Decisions about large swaths of the economy were largely made for military purposes and nearly all relevant inputs were allocated to the war effort. Many goods were rationed, prices and wages controlled and many durable consumer goods were no longer produced. Large segments of the workforce were inducted into the military, paid half wages, and roughly half of those were sent into harm's way.
