 The performance principle, which is that of an acquisitive and antagonistic society in the process of constant expansion, presupposes a long development during which domination has been increasingly rationalized: control over social labor now reproduces society on a large scale and under improving conditions. For a long way, the interests of domination and the interests of the whole coincide: the profitable utilization of the productive apparatus fulfills the needs and faculties of individuals. For the vast majority of the population, the scope and mode of satisfaction are determined by their own labor; but their labor is work for an apparatus which they do not control, which operates as an independent power to which individuals must submit if they want to live. And it becomes the more alien the more specialized the division of labor becomes. Men do not live their own lives but perform pre-established functions. While they work, they do not fulfill their own needs and faculties but work in alienation. (Marcuse 1955: 45)
