In 1949, Crane wrote an angry letter to Hayek about a paper by Frank Knight, “The Determination of Just Wages,” which Knight had written for the Society’s annual meeting. (Knight failed to attend the meeting, so it never was presented publicly.) The paper argued, among other things, that wealth was becoming progressively more concentrated in the United States, a point that Crane denounced as an idea “which stems from Karl Marx."
