Income inequality in the United States

Income inequality has fluctuated considerably in the United States since measurements began around 1915, moving in an arc between peaks in the 1920s and 2000s, with a lower level of inequality from approximately 1950-1980 (a period named the Great Compression), followed by increasing inequality, in what has been coined as the great divergence. The U.S. has the highest level of income inequality among its (post-industrialized) peers.
