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.
Wealth inequality in the United States
Pioneering work by Simon Kuznets using income tax records and his own well-researched estimates of national income showed a reduction of about 10% in the portion of national income going to the top 10%, a reduction from about 45–50% in 1913 to about 30–35% in 1948. This period spans both The Great Depression and World War II, events with significant economic consequences. This is called the Great Compression.
