Economic history of the United States
Panic of 1873 created one of the worst and longest depressions in American history, seriously affecting every aspect of the economy and bringing the railroad expansion to a halt. The New York Stock Exchange closed for ten days. Of the country's 364 railroads, 89 went bankrupt, a total of 18,000 businesses failed between 1873 and 1875, unemployment reached 14% by 1876, during a time which became known in Britain as the Long Depression. Politically, the Democrats took control of Congress in 1874, the election of 1876 was deadlocked.
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.
