Our main way of relating ourselves to others is like things relate themselves to things on the market. We want to exchange our own personality, or as one says sometimes, our "personality package", for something. Now, this is not so true for the manual workers. The manual worker does not have to sell his personality. He doesn't have to sell his smile. But what you might call the "symbolpushers" , that is to say, all the people who deal with figures, with paper, with men, who manipulate - to use a better, or nicer, word - manipulate men and signs and words, all those today have not only to sell their service but in the bargain they're to sell their personality, more or less. There are exceptions.
