By the mid-1930s, the U.S. economy appeared to be climbing out of the (Great Depression). The Dow Jones Industrial Average (DJIA), which had bottomed out at 41 in 1932, was advancing. It increased 73% from the beginning of 1935 through the end of 1936, when it hit 180. The number of (unemployed, 13 million in 1933, dropped to 9.5 million in 1935 and 7.6 million in 1936.
Then, in 1937, the DJIA plunged 33% in what is often called "a depression within a depression." Joblessness skyrocketed.
A principal factor in the (meltdown) that year was the U.S. Supreme Court's surprise 5-4 decision in early April to uphold the (constitutionality) of the Wagner Act, which had passed two years earlier. This measure, which is still the basis of our labor relations (regime), authorized union officials to seek and obtain the power to act as the "exclusive" (that is, the (monopoly)) bargaining agent over all the front-line employees, including union nonmembers as well as members, in a unionized workplace.
