Chap. III. all the displaced labor and capital, the margin of cultivation must, if the same amount of labor and capital press for employment, be carried lower than 18. In this case, rent would gain more than the increase in the product, and wages and interest would be less than before the improvements which increased productive power.

Nor is it precisely true that the labor set free by each improvement will all be driven to seek employment in the production of more wealth. The increased power of satisfaction, which each fresh improvement gives to a certain portion of the community, will be utilized in demanding leisure or services, as well as in demanding wealth. Some laborers will, therefore, become idlers and some will pass from the ranks of productive to those of unproductive laborers—the proportion of which, as observation shows, tends to increase with the progress of society.

But, as I shall presently allude to a cause, as yet unconsidered, which constantly tends to lower the margin of cultivation, to steady the advance of rent, and even carry it beyond the proportion that would be fixed by the actual margin of cultivation, it is not worth while to take into account these perturbations in the downward movement of the margin of cultivation and the upward movement of rent. All I wish to make clear is that, without any increase in population, the progress of invention constantly tends to give a larger and larger proportion of the produce to the owners of land, and a smaller and smaller proportion to labor and capital.

And, as we can assign no limits to the progress of invention, neither can we assign any limits to the increase of rent, short of the whole produce. For, if labor-saving inventions went on until perfection was attained, and the necessity of labor in the production of wealth was entirely done away with, then everything that the earth could yield could be obtained without labor, and the margin of cultivation would be extended to zero. Wages would be nothing, and interest would be nothing, while rent would take everything. For the owners of the land, being enabled without
