"The objective alienation of man from the product and the process of work is entailed by the legal framework of modern capitalism and the modern division of labor. The worker does not own the product or the tools of his production. In the labor contract he sells his time, energy, and skill into the power of others. To understand self-alienation we need not accept the metaphysical view that man's self is most crucially expressed in work-activity. In all work involving the personality market, as we have seen, one's personality and personal traits become part of the means of production. In this sense a person instrumentalizes and externalizes intimate features of his person and disposition. In certain white-collar areas, the rise of personality markets has carried self and social alienation to explicit extremes" (White Collar: The American Middle Classes, 1951, p. 225).
