[T]he most successful Republican of the 20th century up to that time, Dwight D. Eisenhower, had been quite happy with a top income tax rate on millionaires of 91 percent. As he wrote to his brother Edgar Eisenhower in a personal letter on November 8, 1954:That was a marginal tax rate, of course, but still worth noting.
[T]o attain any success it is quite clear that the Federal government cannot avoid or escape responsibilities which the mass of the people firmly believe should be undertaken by it. The political processes of our country are such that if a rule of reason is not applied in this effort, we will lose everything–even to a possible and drastic change in the Constitution. This is what I mean by my constant insistence upon ‘moderation’ in government. Should any political party attempt to abolish social security, unemployment insurance, and eliminate labor laws and farm programs, you would not hear of that party again in our political history. There is a tiny splinter group, of course, that believes you can do these things. Among them are H. L. Hunt [you possibly know his background], a few other Texas oil millionaires, and an occasional politician or business man from other areas. Their number is negligible and they are stupid.
