For a complex illustration, consider a railway passenger car. It is Wealth because it is an Artificial Object produced by Labor from and upon Land. But does it fall into that subdivision of Wealth which is distinguished as Capital--Wealth used for the production of more Wealth? As to its owners it is Capital, for they are using it to increase their share of Wealth in process of production; but as to the aggregate of social Wealth, its passengers, if not using it for productive purposes, are consuming Wealth unproductively. To the extent that the passengers are not on productive missions, but are gratifying their own wants, a passenger-car is in Economic contemplation Wealth in process of ultimate consumption to satisfy wants; to the extent that its passengers are on productive missions it is Wealth devoted to the Production of more Wealth, and therefore in the subcategory which is distinguished as Capital. The fact that part of its use is for Production and another for enjoyment does not disturb the principle which distinguishes Capital from Wealth in process of ultimate consumption for the satisfaction of wants. Capital is Wealth in forms that are consumed in the further or better production of Wealth toward final forms for ultimate consumption. To save such Wealth in the sense of preventing its consumption would be to waste it; but to permit its consumption in the Productive Process is to give it serviceability. So with all other details of the Productive Process, from natural raw materials to and including delivery to ultimate consumers. Capital is produced by Labor from and upon Land and in forms of Wealth--either Artificial materials or Artificial contrivances--which, being adapted and devoted to further Production of Wealth, are part of Labor’s artificial materials or mechanism or both--Wealth produced for augmenting Productive power. In Economic phrasing, Wealth used in the Production of Wealth is Capital. 2--_Trade_ Another prominent sub-classification of secondary facts involved in the Productive Process is inseparably associated with Capital. This subordinate category is Trade, to which our attention was directed in the second stage of our delving down from the surface of Economics to its Basic Facts.
