It is widely agreed that the productivity growth of the industrialized economies is mainly an ongoing intellectual achievement, a sustained flow of new ideas. Are these ideas the achievements of a few geniuses, Newton, Beethoven, and a handful of others, viewed as external to the activities of ordinary people? Are they the product of a specialized research sector, engaged in the invention of patent-protected processes over which they have monopoly rights? Both images are based on important features of reality and both have inspired interesting growth theories, but neither seems to me central. What is central, I believe, is that fact that the industrial revolution involved the emergence (or rapid expansion) of a class of educated people, thousands–now many millions–of people who spend entire careers exchanging ideas, solving work-related problems, generating new knowledge.
