By colloquial usage and in business accounts the word “wealth”--“capital” when used as a sub-classification of Wealth, that is, Wealth devoted to the production of more Wealth--has taken on a variety of misleading connotations. In business accounts, for example, whatever will bring a price to the owner is accounted Wealth, or Capital as a sub-classification of Wealth, whether the object of the price be a building, a domesticated animal, a slave, a vacant building-lot, an unused agricultural area, or an improved and cultivated farm. Some of those items of “wealth” or “capital” do belong, Economically, in the Wealth category, buildings and domesticated animals being among them; but many fall wholly or in part into one or the other of the two other categories, Labor and Land. Evidently the science of Economics, which comprehends the interests of all and not merely those of a private business, cannot classify slaves as Wealth. Since they are not and cannot be Artificial Objects, but are human beings, they belong of necessity in the Man or Labor category. They differ radically from animals. In the wild state animals belong Economically in the category of Land (Natural Resources) as truly as wild vegetation does; in the domesticated state they are Wealth (Artificial Objects) as truly as produced vegetation is; and if used to produce Wealth they are Capital (Wealth used for the production of Wealth) as truly as machinery is. But slaves in their “wild state” are not Natural Resources for the use of Man, as wild animals are; they are human beings, and as such they belong in the Man category. As used in business accounts and colloquially, the word “wealth” does, as indicated above, include some kinds of true Economic Wealth, such as “store goods,” buildings, farm produce, machinery and other Artificial Objects. But in those undiscriminating uses it also includes such Natural Resources (Land) as mineral deposits, water fronts, building sites, railroad rights of way; also mere titles to various kinds of property interests, such as bonds, mortgages, deeds, bank balances, money in hand and corporation stocks.
