MY DEAR SIR,
If your statement[93] was correct, this extravagant consequence would follow from it: That in proportion as population increased and worse land was brought under cultivation, the proportion of produce to the corn expenses of procuring it would increase. If we now had twenty millions of quarters with an expense of five millions of quarters, we should when we expended ten millions of quarters obtain more than forty[94], notwithstanding that in the latter period many more than double the quantity of hands were employed in cultivation in consequence of the poorer quality of the land. If this be true, the principle of population is false, because the more you increase the people, the greater surplus of abundance will appear. Your statement is however very ingenious, and carries a great deal of plausibility with it; but I think you err in supposing it possible that the proportion of the whole corn expenditure to the produce obtained can fall, with an increase of the price of corn. The two are incompatible; either the whole corn expenses of production will be increased or not. If they be, the price of corn will rise; but, if they be not, I can see no reason for a rise in the price of corn. I admit that it is only the last portion of capital employed on the land which will be attended with an increased corn expense; but, unless it renders the whole produce together at an increased expense, the price of produce will not rise. Suppose the produce of the country ten millions of quarters with the price at £4 per quarter, the number of labourers employed two-and-a-half millions, each receiving two quarters of corn annually as wages. Suppose too that the population increases and five millions of quarters more are required, but that it cannot be obtained with less labour than that of two millions of men. If we suppose the price to increase in proportion to the number of men employed, it will rise to £4 16s., because to raise ten millions of quarters an average of three millions of men would be now required instead of two-and-a-half millions. Suppose now each man to consume one quarter annually for food and to exchange the remainder for other necessaries. Fourteen bushels will be sufficient wages for him[95]; the expenditure of corn for wages will then be for fifteen millions of produce 7.875.000, and for ten millions 5.250.000. Before, it was only five millions; consequently the proportion of surplus produce has diminished.
