[T]he less the material and labor that the production of a jacket costs, the more jackets, of course, can one produce with the means of production available. Thus the more completely can the need for clothing be satisfied. And thus, other things being equal, the lower will be the marginal utility of a jacket. The technical conditions of production are, therefore, to be sure a cause of the value of goods lying further back, a "more ultimate" cause, than marginal utility.
