the fact that, although not the first to announce it, he first brought it prominently into notice.34 It is:

The rent of land is determined by the excess of its produce over that which the same application can secure from the least productive land in use.

This law, which of course applies to land used for other purposes than agriculture, and to all natural agencies, such as mines, fisheries, etc., has been exhaustively explained and illustrated by all the leading economists since Ricardo. But its mere statement has all the force of a self-evident proposition, for it is clear that the effect of competition is to make the lowest reward for which labor and capital will engage in production, the highest that they can claim; and hence to enable the owner of more productive land to appropriate in rent all the return above that required to recompense labor and capital at the ordinary rate⁠—that is to say, what they can obtain upon the least productive land in use, or at the least productive point, where, of course, no rent is paid.

Perhaps it may conduce to a fuller understanding of the law of rent to put it in this form: The ownership of a natural agent of production will give the power of appropriating so much of the wealth produced by the exertion of labor and capital upon it as exceeds the return which the same application of labor and capital could secure in the least productive occupation in which they freely engage.

This, however, amounts to precisely the same thing, for there is no occupation in which labor and capital can engage which does not require the use of land; and, furthermore, the cultivation or other use of land will always be carried to as low a point of remuneration, all things considered, as is freely accepted in any other pursuit. Suppose, for instance, a community in which part of the labor and capital is devoted to agriculture and part to manufactures. The poorest land cultivated yields an average return which we will call 20, and 20 therefore will be the average return to labor and capital, as well in manufactures as in agriculture. Suppose that from some permanent cause the return in manufactures is now reduced to 15. Clearly, the labor and capital engaged in manufactures will turn to agriculture; and the process will not stop until, either by the extension of cultivation to inferior lands or to inferior points on the same land, or by an increase in the relative value of manufactured products, owing to the diminution of production⁠—or, as a matter of fact, by both processes⁠—the yield to labor and capital in both pursuits has, all things considered, been brought again to the same level, so that whatever be the final point of productiveness at which manufactures are still carried on, whether it be 18 or 17 or 16, cultivation will also be extended to that point. And, thus, to say that rent will be the excess in productiveness over the yield at the margin, or lowest point, of cultivation, is the same thing as to say that it will be the excess of produce over what the same amount of labor and capital obtains in the least remunerative occupation.

The law of rent is, in fact, but a deduction from the law of competition, and amounts simply to the assertion that as wages and interest tend to a common level, all that part of the general production of wealth which exceeds what the labor and capital employed could have secured for themselves, if applied to the poorest natural agent in use, will go to land owners in the shape of rent. It rests, in the last analysis, upon the fundamental principle, which is to political economy what the attraction of gravitation is to physics⁠—that men will seek to gratify their desires with the least exertion.

This, then, is the law of rent. Although many standard treatises follow too much the example of Ricardo, who seems to view it merely in its relation to agriculture, and in several places speaks of manufactures yielding no rent, when, in truth, manufactures and exchange yield the highest rents, as is evinced by the greater value of land in manufacturing and commercial cities, thus hiding the full importance of the law, yet, ever since the time of Ricardo, the law itself has been clearly apprehended and fully recognized. But not so its corollaries. Plain as they are, the accepted doctrine of wages (backed and fortified not only as has been hitherto explained, but by considerations whose enormous weight will be seen when the logical conclusion toward which we are tending is reached) has hitherto prevented their recognition.35 Yet, is it not as plain as the simplest geometrical demonstration, that the corollary of the law of rent is the law of wages, where the division of the produce is simply between rent and wages; or the law of wages and interest taken together, where the division is into rent, wages, and interest? Stated reversely, the law of rent is necessarily the law of wages and interest taken together, for it is the assertion, that no matter what be the production which results from the application of labor and capital, these two factors will receive in wages and interest only such part of the produce as they could have produced on land free to them without the payment of rent⁠—that is, the least productive land or point in use. For, if, of the produce, all over the amount which labor and capital could secure from land for which no rent is paid must go to land owners as rent, then all that can be claimed by labor and capital as wages and interest is the amount which they could have secured from land yielding no rent.

Or to put it in algebraic form:

As Produce = Rent + Wages + Interest,

Therefore, Produce-Rent = Wages + Interest.

Thus wages and interest do not depend upon
