THE UNITY OF THE ECONOMY
However, despite its extreme differentiation and manifold contrasts, the economic process of today is actually a whole. It is not a unit in the true sense of the term; and yet it functions with an all-embracing homogeneity which may be idealized and represented as unity. This condition is founded in production. All productive stems are related to one another. The products of the stem of unskilled labor are more than the products of labor. A similar statement may be made for those of the soil. Both groups belong to other stems as well and are productively related to their products. Some products have all stems in common, fully related products one might call them. A table and a chest made by a carpenter of the same kind of wood and other materials thruout are examples. Others are only partially related; they have only certain stems or some one stem in common. But it would scarcely be possible to' name one product which has no such connection with any one of the many other goods in use. There may be specific instances of products which have no stem in common. But in such instances one finds some third commodity which establishes an indirect relationship between the first two because they both have some stem in common with it. The intimate affiliation of productive groups, all of which ultimately coalesce into one all-embracing productive body, is fittingly described by their accepted designation, branches of production.
