The evil of reducing labor

Hazlitt on the "evils" of job losses due to technological progress:

If it were indeed true that the introduction of labor-saving machinery is a cause of constantly mounting unemployment and misery, the logical conclusions to be drawn would be revolutionary, not only in the technical field but for our whole concept of civilization. Not only should we have to regard all further technical progress as a calamity; we should have to regard all past technical progress with equal horror. Every day each of us in his own activity is engaged in trying to reduce the effort it requires to accomplish a given result. Each of us is trying to save his own labor, to economize the means required to achieve his ends. Every employer, small as well as large, seeks constantly to gain his results more economically and efficiently—that is, by saving labor. Every intelligent workman tries to cut down the effort necessary to accomplish his assigned job. The most ambitious of us try tirelessly to increase the results we can achieve in a given number of hours. The technophobes, if they were logical and consistent, would have to dismiss all this progress and ingenuity as not only useless but vicious. Why should freight be carried from Chicago to New York by railroad when we could employ enormously more men, for example, to carry it all on their backs?
