42. Franklin Delano Roosevelt
Saving the world isn't enough?
WWII was won by the Allies, not just the United States. And really, when we were involved in WWII, FDR began halting some of his New Deal plans. At the time of his death, taxes on people who made $200,000 a year ranged around 90%. After 1945, taxes were cut to around 30% for this income bracket. This is when the economy really started to rebound in the United States. Coincidence? Not really.
And FDR was part of the allies. Therefore, he saved the world.
