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.
History of taxation in the United States
During the outbreak of the Great Depression in 1930, Congress raised tariffs via the Smoot-Hawley Tariff Act on over 20,000 imported goods to record levels, and, in the opinion of most economists, worsened the Great Depression by causing other countries to reciprocate thereby plunging American imports and exports by more than half.
