"Keynes was quite frequently in Washington during the war on some negotiating mission. Anybody who's had experience with diplomatic negotiating matters knows that it's an exercise in idleness. You're waiting for instructions from your government, you're waiting for the others to be instructed; you're waiting for a meeting. Keynes filled in those times by moving into the American meeting. By this time there was a sizable group of younger people, of whom I was one, who were devoted to his ideas ― a much larger group, as he has said, in Washington than he had in London. His vanity was not above being touched by this effect, so he brought around him a group of younger Washington people for discussion of wartime policy, and I was naturally in that group."
