the distribution of wealth, let us, therefore, consider the effects of increase of population apart from improvement in the arts, and then the effect of improvement in the arts apart from increase of population. II The Effect of Increase of Population Upon the Distribution of Wealth

The manner in which increasing population advances rent, as explained and illustrated in current treatises, is that the increased demand for subsistence forces production to inferior soil or to inferior productive points. Thus, if, with a given population, the margin of cultivation is at 30, all lands of productive power over 30 will pay rent. If the population be doubled, an additional supply is required, which cannot be obtained without an extension of cultivation that will cause lands to yield rent that before yielded none. If the extension be to 20, then all the land between 20 and 30 will yield rent and have a value, and all land over 30 will yield increased rent and have increased value.

It is here that the Malthusian doctrine receives from the current elucidations of the theory of rent the support of which I spoke when enumerating the causes that have combined to give that doctrine an almost undisputed sway in current thought. According to the Malthusian theory, the pressure of population against subsistence becomes progressively harder as population increases, and although two hands come into the world with every new mouth, it becomes, to use the language of John Stuart Mill, harder and harder for the new hands to supply the new mouths. According to Ricardo’s theory of rent, rent arises from the difference in productiveness of the lands in use, and as explained by Ricardo and the economists who have followed him, the advance in rents which, experience shows, accompanies increasing population, is caused by the inability of procuring more food except at a greater cost, which thus forces the margin of population to lower and lower points of production, commensurately increasing rent. Thus the two theories, as I have before explained, are made to harmonize and blend, the law of rent becoming but a special application of the more general law propounded by Malthus, and the advance of rents with increasing population a demonstration of its resistless operation. I refer to this incidentally, because it now lies in our way to see the misapprehension which has enlisted the doctrine of rent in the support of a theory to which it in reality gives no countenance. The Malthusian theory has been already disposed of, and the cumulative disproof which will prevent the recurrence of a lingering doubt will be given when it is shown, further on, that the phenomena attributed to the pressure of population against subsistence would, under existing conditions, manifest themselves were population to remain stationary.

The misapprehension to which I now refer, and which, to a proper understanding of the effect of increase of population upon the distribution of wealth, it is necessary to clear up, is the presumption, expressed or implied in all the current reasoning upon the subject of rent in connection with population, that the recourse to lower points of production involves a smaller aggregate produce in proportion to the labor expended; though that this is not always the case is clearly recognized in connection with agricultural improvements, which, to use the words of Mill, are considered “as a partial relaxation of the bonds which confine the increase of population.” But it is not involved even where there is no advance in the arts, and the recourse to lower points of production is clearly the result of the increased demand of an increased population. For increased population, of itself, and without any advance in the arts, implies an increase in the productive power of labor. The labor of 100 men, other things being equal, will produce much more than one hundred times as much as the labor of one man, and the labor of 1,000 men much more than ten times as much as the labor of 100 men; and, so, with every additional pair of hands which increasing population brings, there is a more than proportionate addition to the productive power of labor. Thus, with an increasing population, there may be a recourse to lower natural powers of production, not only without any diminution in the average production of wealth as compared to labor, but without any diminution at the lowest point. If population be doubled, land of but 20 productiveness may yield to the same amount of labor as much as land of 30 productiveness could before yield. For it must not be forgotten (what often is forgotten) that the productiveness either of land or labor is not to be measured in any one thing, but in all desired things. A settler and his family may raise as much corn on land a hundred miles away from the nearest habitation as they could raise were their land in the center of a populous district. But in the populous district they could obtain with the same labor as good a living from much poorer land, or from land of equal quality could make as good a living after paying a high rent, because in the midst of a large population their labor would have become more effective; not, perhaps, in the production of corn, but in the production of wealth generally⁠—or the obtaining of all the commodities and services which are the real object of their labor.

But even where there is a diminution in the productiveness of labor at the lowest point⁠—that is to say, where the increasing demand for wealth has driven production to a lower point of natural productiveness than the addition to the power of labor from increasing population suffices to make up for⁠—it does not follow that the aggregate production, as compared with the aggregate labor, has been lessened.

Let us suppose land of diminishing qualities. The best would naturally be settled first, and as population increased production would take in the next lower quality,
