All such terms as “salaries,” “commissions,” “labor costs,” and the like in private or business accounts, are in the Wages category of Economics. “Profits” and “dividends” are mixed, very much as with reference to the Productive Process in private and business accounts Wealth and Land are mixed. “Profits” may be and they usually are made up of a mixture of Wages for human service (Labor) and of Rent for natural resources (Land). Convenient as such confused classifications may be for account-keeping in private business affairs, or for other manifestations of mere custom, they have no legitimate place in the orderly categories of social Economics. However useful in business accountings, which concern only the private interests of business proprietors, they are intolerable in the science of Economics, which concerns not only a proprietor, nor every proprietor, but all mankind. Even for private accounting purposes there seems to be a wise tendency among accountants toward more accurate assignments to normal Economic categories. One business classification holds high Economic rank deservedly. This is that subcategory of Wages known as Interest. Interest may be rightly regarded as the Wages of Capital. This is no play upon words, nor any confusion of Economic terms. It is a necessary inference from manifest facts. Since Labor produces all Wealth, and Capital is a distinct form of Wealth--Wealth devoted to the production of further Wealth,--Labor is the producer of Capital; and inasmuch as the use productively of Capital increases Wealth, a share of that increase is properly assignable in Distribution to the Distributive category called Wages, though for discriminative purposes to a Wages subdivision. That subdivision is distinguished as Interest. It is a subdivision in Distribution in perfect correspondence with that subdivision of Wealth used in Production which is distinguished as Capital. As subdivisions or secondary classifications, therefore, the productive factor known as Capital and the corresponding Distributive element known as Interest are legitimate Economic categories, provided their Economic characteristic as products of Labor be not ignored nor they be confused with Land and Rent. This proviso is often ignored, however, as when Capital is classified with Land instead of Labor, and Interest with Rent instead of Wages. In connection with the subject of Wages, Taxation for the support of Government demands passing consideration. If it be true, as indicated in our Lesson on the Productive Process, that the legitimate activities of Government belong in the Wealth production category as a Labor factor, then the Economically legitimate income of Government, whether through Taxation or otherwise, would seem to belong to the Distributive category of Wages.
