The Great Compression refers to the period of substantial wage compression in the United States that began in the early 1940s. During that time, economic inequality as shown by wealth distribution and income distribution between the rich and poor became much smaller than it had been in preceding time periods. The term was reportedly coined by Claudia Goldin and Robert Margo in a 1992 paper, and is a takeoff on the Great Depression, an event during which the Great Compression started.
