Homo economicus
This comment seems to suggest a sort of rational, self-interested, labor-averse individual. However, in Book V, Chapter I, Smith argues, "The man whose whole life is spent in performing a few simple operations, of which the effects are perhaps always the same, or very nearly the same, has no occasion to exert his understanding or to exercise his invention in finding out expedients for removing difficulties which never occur. He naturally loses, therefore, the habit of such exertion, and generally becomes as stupid and ignorant as it is possible for a human creature to become." Smith not only excoriates division of labor and "Homo economicus" but even prefigures Marx's theory of alienation of labor. Thus, his opening paragraph sets up the standard conception of work specialization only to shatter it later on.
