Until he was able to get us into WWII, after promising that he would not.He also got away with it politically by blaming his predecessor.
The Depression ended when Roosevelts heart stopped beating. He was our version of a leftist dictator. Only the Constitution and the Supreme Court kept us from going completely totalitarian.
Roosevelt had many people so brainwashed, there were soldiers/Marines who, upon hearing of his death, said sorrowfully, "Now the war will never end."He had people thinking inside the box, big time.
My FIL fought in the US Army until the end of the war in Europe. He became an LEO and retired after many years service and was a conservative in almost every fiber of his being.
We were talking one evening and the subject of FDR came up, he worshiped FDR and I was astounded, I would never have believed it if I hadn't heard it from him. I didn't argue the issue because he was a great guy and I believe him going through the depression and his Dad losing most everything he had had a lot to do with it.
