Progress and Poverty, Volumes I and II / An Inquiry into the Cause of Industrial Depressions and of Increase of Want with Increase of Wealth

by Henry George

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, and so on. But, as the increase of population, by permitting greater economies, adds to the effectiveness of labor, the cause which brought each quality of land successively into cultivation would at the same time increase the amount of wealth that the same quality of labor could produce from it. But it would also do more than this—it would increase the power of producing wealth on all the superior lands already in cultivation. If the relations of quantity and quality were such that increasing population added to the effectiveness of labor faster than it compelled a resort to less productive qualities of land, though the margin of cultivation would fall and rent would rise, the minimum return to labor would increase. That is to say, though wages as a proportion would fall, wages as a quantity would rise. The average production of wealth would increase. If the relations were such that the increasing effectiveness of labor just compensated for the diminishing productiveness of the land as it was called into use, the effect of increasing population would be to increase rent by lowering the margin of cultivation without reducing wages as a quantity, and to increase the average production. If we now suppose population still increasing, but, between the poorest quality of land in use and the next lower quality, to be a difference so great that the increased power of labor which comes with the increased population that brings it into cultivation cannot compensate for it—the minimum return to labor will be reduced, and with the rise of rents, wages will fall, not only as a proportion, but as a quantity. But unless the descent in the quality of land is far more precipitous than we can well imagine, or than, I think, ever exists, the average production will still be increased, for the increased effectiveness which comes by reason of the increased population that compels resort to the inferior quality of land attaches to all labor, and the gain on the superior qualities of land will more than compensate for the diminished production on the quality last brought in. The aggregate wealth production, as compared with the aggregate expenditure of labor, will be greater, though its distribution will be more unequal.

Thus, increase of population, as it operates to extend production to lower natural levels, operates to increase rent and reduce wages as a proportion, and may or may not reduce wages as a quantity; while it seldom can, and probably never does, reduce the aggregate production of wealth as compared with the aggregate expenditure of labor, but on the contrary increases, and frequently largely increases it.

But while the increase of population thus increases rent by lowering the margin of cultivation, it is a mistake to look upon this as the only mode by which rent advances as population grows. Increasing population increases rent, without reducing the margin of cultivation; and notwithstanding the dicta of such writers as McCulloch, who assert that rent would not arise were there an unbounded extent of equally good land, increases it without reference to the natural qualities of land, for the increased powers of co-operation and exchange which come with increased population are equivalent to—nay, I think we can say without metaphor, that they give—an increased capacity to land.

I do not mean to say merely that, like an improvement in the methods or tools of production, the increased power which comes with increased population gives to the same labor an increased result, which is equivalent to an increase in the natural powers of land; but that it brings out a superior power in labor, which is localized on land—which attaches not to labor generally, but only to labor exerted on particular land; and which thus inheres in the land as much as any qualities of soil, climate, mineral deposit, or natural situation, and passes, as they do, with the possession of the land.

An improvement in the method of cultivation which, with the same outlay, will give two crops a year in place of one, or an improvement in tools and machinery which will double the result of labor, will manifestly, on a particular piece of ground, have the same effect on the produce as a doubling of the fertility of the land. But the difference is in this respect—the improvement in method or in tools can be utilized on any land; but the improvement in fertility can be utilized only on the particular land to which it applies. Now, in large part, the increased productiveness of labor which arises from increased population can be utilized only on particular land, and on particular land in greatly varying degrees.

Here, let us imagine, is an unbounded savannah, stretching off in unbroken sameness of grass and flower, tree and rill, till the traveler tires of the monotony. Along comes the wagon of the first immigrant. Where to settle he cannot tell—every acre seems as good as every other acre. As to wood, as to water, as to fertility, as to situation, there is absolutely no choice, and he is perplexed by the embarrassment of richness. Tired out with the search for one place that is better than another, he stops—somewhere, anywhere—and starts to make himself a home. The soil is virgin and rich, game is abundant, the streams flash with the finest trout. Nature is at her very best. He has what, were he in a populous district, would make him rich; but he is very poor. To say nothing of the mental craving, which would lead him to welcome the sorriest stranger, he labors under all the material disadvantages of solitude. He can get no temporary assistance for any work that requires a greater union of strength than that afforded by his own family, or by such help as he can permanently keep. Though he has cattle, he cannot often have fresh meat, for to get a beefsteak he must kill a bullock. He must be his own blacksmith, wagonmaker, carpenter, and cobbler—in short, a “jack of all trades and master of none.” He cannot have his children schooled, for, to do so, he must himself pay and maintain a teacher. Such things as he cannot produce himself, he must buy in quantities and keep on hand, or else go without, for he cannot be constantly leaving his work and making a long journey to the verge of civilization; and when forced to do so, the getting of a vial of medicine or the replacement of a broken auger may cost him the labor of himself and horses for days. Under such circumstances, though nature is prolific, the man is poor. It is an easy matter for him to get enough to eat; but beyond this, his labor will suffice to satisfy only the simplest wants in the rudest way.
