When we speak of a community increasing in wealth—as when we say that England has increased in wealth since the accession of Victoria, or that California is a wealthier country than when it was a Mexican territory—we do not mean to say that there is more land, or that the natural powers of the land are greater, or that there are more people, for when we wish to express that idea we speak of increase of population; or that the debts or dues owing by some of these people to others of their number have increased; but we mean that there is an increase of certain tangible things, having an actual and not merely a relative value—such as buildings, cattle, tools, machinery, agricultural and mineral products, manufactured goods, ships, wagons, furniture, and the like. The increase of such things constitutes an increase of wealth; their decrease is a lessening of wealth; and the community that, in proportion to its numbers, has most of such things is the wealthiest community. The common character of these things is that they consist of natural substances or products which have been adapted by human labor to human use or gratification, their value depending on the amount of labor which upon the average would be required to produce things of like kind. Thus wealth, as alone the term can be used in political economy, consists of natural products that have been secured, moved, combined, separated, or in other ways modified by human exertion, so as to fit them for the gratification of human desires. It is, in other words, labor impressed upon matter in such a way as to store up, as the heat of the sun is stored up in coal, the power of human labor to minister to human desires. Wealth is not the sole object of labor, for labor is also expended in ministering directly to desire; but it is the object and result of what we call productive labor—that is, labor which gives value to material things. Nothing which nature supplies to man without his labor is wealth, nor yet does the expenditure of labor result in wealth unless there is a tangible product which has and retains the power of ministering to desire. Now, as capital is wealth devoted to a certain purpose, nothing can be capital which does not fall within this definition of wealth. By recognizing and keeping this in mind, we get rid of misconceptions which vitiate all reasoning in which they are permitted, which befog popular thought, and have led into mazes of contradiction even acute thinkers. But though all capital is wealth, all wealth is not capital. Capital is only a part of wealth—that part, namely, which is devoted to the aid of production. It is in drawing this line between the wealth that is and the wealth that is not capital that a second class of misconceptions are likely to occur.
