As commonly used the word “wealth” is applied to anything having an exchange value. But when used as a term of political economy it must be limited to a much more definite meaning, because many things are commonly spoken of as wealth which in taking account of collective or general wealth cannot be considered as wealth at all. Such things have an exchange value, and are commonly spoken of as wealth, insomuch as they represent as between individuals, or between sets of individuals, the power of obtaining wealth; but they are not truly wealth, inasmuch as their increase or decrease does not affect the sum of wealth. Such are bonds, mortgages, promissory notes, bank bills, or other stipulations for the transfer of wealth. Such are slaves, whose value represents merely the power of one class to appropriate the earnings of another class. Such are lands, or other natural opportunities, the value of which is but the result of the acknowledgment in favor of certain persons of an exclusive right to their use, and which represents merely the power thus given to the owners to demand a share of the wealth produced by those who use them. Increase in the amount of bonds, mortgages, notes, or bank bills cannot increase the wealth of the community that includes as well those who promise to pay as those who are entitled to receive. The enslavement of a part of their number could not increase the wealth of a people, for what the enslavers gained the enslaved would lose. Increase in land values does not represent increase in the common wealth, for what land owners gain by higher prices, the tenants or purchasers who must pay them will lose. And all this relative wealth, which, in common thought and speech, in legislation and law, is undistinguished from actual wealth, could, without the destruction or consumption of anything more than a few drops of ink and a piece of paper, be utterly annihilated. By enactment of the sovereign political power debts might be canceled, slaves emancipated, and land resumed as the common property of the whole people, without the aggregate wealth being diminished by the value of a pinch of snuff, for what some would lose others would gain. There would be no more destruction of wealth than there was creation of wealth when Elizabeth Tudor enriched her favorite courtiers by the grant of monopolies, or when Boris Godoonof made Russian peasants merchantable property. All things which have an exchange value are, therefore, not wealth, in the only sense in which the term can be used in political economy. Only such things can be wealth the production of which increases and the destruction of which decreases the aggregate of wealth. If we consider what these things are, and what their nature is, we shall have no difficulty in defining wealth.
