It will be necessary to review in its main branches the whole subject of the distribution of wealth. To discover the cause which, as population increases and the productive arts advance, deepens the poverty of the lowest class, we must find the law which determines what part of the produce is distributed to labor as wages. To find the law of wages, or at least to make sure when we have found it, we must also determine the laws which fix the part of the produce which goes to capital and the part which goes to land owners, for as land, labor, and capital join in producing wealth, it is between these three that the produce must be divided. What is meant by the produce or production of a community is the sum of the wealth produced by that community—the general fund from which, as long as previously existing stock is not lessened, all consumption must be met and all revenues drawn. As I have already explained, production does not merely mean the making of things, but includes the increase of value gained by transporting or exchanging things. There is a produce of wealth in a purely commercial community, as there is in a purely agricultural or manufacturing community; and in the one case, as in the others, some part of this produce will go to capital, some part to labor, and some part, if land have any value, to the owners of land. As a matter of fact, a portion of the wealth produced is constantly going to the replacement of capital, which is constantly consumed and constantly replaced. But it is not necessary to take this into account, as it is eliminated by considering capital as continuous, which, in speaking or thinking of it, we habitually do. When we speak of the produce, we mean, therefore, that part of the wealth produced above what is necessary to replace the capital consumed in production; and when we speak of interest, or the return to capital, we mean what goes to capital after its replacement or maintenance. It is, further, a matter of fact, that in every community which has passed the most primitive stage some portion of the produce is taken in taxation and consumed by government. But it is not necessary, in seeking the laws of distribution, to take this into consideration. We may consider taxation either as not existing, or as by so much reducing the produce. And so, too, of what is taken from the produce by certain forms of monopoly, which will be considered in a subsequent chapter (Chap. IV), and which exercise powers analogous to taxation. After we have discovered the laws of distribution we can then see what bearing, if any, taxation has upon them. We must discover these laws of distribution for ourselves—or, at least, two out of the three. For, that they are not, at least as a whole, correctly apprehended by the current political economy, may be seen, irrespective of our preceding examination of one of them, in any of the standard treatises. This is evident, in the first place, from the terminology employed.
