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.
Great Depression
Between 1933 and 1939, federal expenditure tripled, and Roosevelt's critics charged that he was turning America into a socialist state. The Great Depression was a main factor in the implementation of social democracy and planned economies in European countries after World War II (see Marshall Plan). Keynesianism generally remained the most influential economic school in the United States and in parts of Europe until the periods between the 1970s and the 1980s, when Milton Friedman and other neoliberal economists formulated and propagated the newly created theories of neoliberalism and incorporated them into the Chicago School of Economics as an alternative approach to the study of economics. Neoliberalism went on to challenge the dominance of the Keynesian school of Economics in the mainstream academia and policy-making in the United States, having reached its peak in popularity in the election of the presidency of Ronald Reagan in the United States, and Margaret Thatcher in the United Kingdom.
