Many say the had FDR not cut back on spending, the 1937 recession won't happen and there won't be any resurgence of the Conservative Coalition in 1938, even with the court-packing bonanza, and so, the New Deal Coalition would be even more dominant in such a scenario.
Some even say that had that happened, a National Health Insurance and other economically progressive policies would be enacted.
Are these true? If so, how can these happen?
