What is the greatest horror that a worker suffers? Do you think that is true?

According to the author, the greatest horror that a worker suffers is the loss of individuality, even of being a person. The worker becomes identified with the machines, and completely divorced from what he makes. He becomes just another material good, and as such, he can be bought and sold. This is not to say that he becomes a slave, but that his personality is absorbed into the machine, and that his time can be traded. He becomes, in Paz's words, "a laborer, which is an abstract noun designating a mere function rather than a specific job (Chapter Four, page 67). I think that Paz makes a compelling argument in that regard. The worker, as a farmer or a small-town businessman, had much more personality earlier. He chose what to plant and when, what supplies to stock and how much, and he determined his lifestyle. As an industrial worker, he no longer has those privileges. He performs the tasks assigned to him during the mandated hours. Tragically, he has lost much of the personality and individuality that he previously had.
