Schumpeter distinguished the static picture of capitalism in the textbook model, with the dynamic reality captured in the process of creative destruction. Apparently Ronald Reagan also understood that a dynamic view is better than a static snapshot. Michael Deaver recounts:
(p. 75) . . . I told him that I noticed his aversion to sitting for photo shoots. He looked at me surprised. "That’s funny, in all these years, nobody’s ever noticed that." I asked him to elaborate. "Well, you can never recover from a still shot."
Reagan was most comfortable with moving film, he went on to say. He truly believed the television camera was a friend, a device that would separate the real from the phony. Still cameras could always be used to make a candidate look like a fool. When he explained this to me in the (p. 76) late 1960s, he said, "You know how I sometimes touch my nose before I make a point? Well, a still shot would show me picking my nose, while a live shot would show me making my point."
