“Twenty years ago, H. Dubreuil, a foreign observer of U.S. industry, could write that Taylor’s ‘insufficiency’ shows up when he comes to approach ‘the inner forces contained in the worker’s soul. . . ‘ That is no longer true. The new (social) scientific management begins precisely where Taylor left off or was incomplete; students of ‘human relations in industry’ have studied not lighting and clean toilets, but social cliques and good morale. For in so far as human factors are involved in efficient and untroubled production, the managerial demiurge must bring them under control. So, in factory and in office, the world to be managed increasingly includes the social setting, the human affairs, and the personality of man as worker”
