The Republican Great Depression of 1929-1939 has been an unending source of mystery, fascination, and disinformation for the past four generations. As you’re reading these words, there’s a huge push on by conservative think-tanks and wealthy political activists to reinvent the history, suggesting that Roosevelt prolonged the Depression or that New Deal programs were ineffective. At the same time, folks like David Sirota are valiantly pushing back with actual facts and statistics, showing that Roosevelt’s New Deal was startlingly effective, particularly when compared with the Republican policies of 1920-1929 that formed the bubble that crashed in 1929, and the Republican failures to deal with its consequences during the last three years of the Herbert Hoover administration (1929-1933).
