He is worth the read, and the way his argument travelled keeps proving it. Max Eastman arranged a condensation for Reader's Digest in April 1945, twenty pages, with a press run in the millions. Look ran a picture-book version that February, and General Motors later handed it out as a pamphlet. So the piece that carried the case passed through editors and sponsors who had their own reasons for moving it, and the picture-book is the end of that line: the conclusion travels and the reasoning does not. That is the question he asks in the 1949 essay, one level down. Why the case was lost among the people who shape opinion, rather than among economists who could have checked it. The channel decides the outcome, and the channel gets chosen by whoever wants the argument to move.
