Raw produce is not at a monopoly price, because the market price of barley and wheat is as much regulated by their cost of production, as the market price of cloth and linen. The only difference is this, that one portion of the capital employed in agriculture regulates the price of corn, namely, that portion which pays no rent; whereas, in the production of manufactured commodities, every portion of capital is employed with the same results; and as no portion pays rent, every portion is equally a regulator of price: corn, and other raw produce, can be augmented too in quantity, by the employment of more capital on the land, and therefore they are not at a monopoly price. There is competition among the sellers, as well as amongst the buyers. This is not the case in the production of those rare wines, and those valuable specimens of art, of which we have been speaking; their quantity cannot be increased, and their price is limited only by the extent of the power and will of the purchasers. The rent of these vineyards may be raised beyond any moderately assignable limits, because no other land being able to produce such wines, none can be brought into competition with them. The corn and raw produce of a country, may indeed for a time sell at a monopoly price; but they can do so permanently only when no more capital can be profitably employed on the lands, and when, therefore, their produce cannot be increased. At such time, every portion of land in cultivation, and every portion of capital employed on the land will yield a rent, differing indeed in proportion to the difference in the return. At such a time too, any tax which may be imposed on the farmer, will fall on rent, and not on the consumer. He cannot raise the price of his corn, because, by the supposition, it is already at the highest price at which the purchasers will or can buy it. He will not be satisfied with a lower rate of profits, than that obtained by other capitalists, and, therefore, his only alternative will be to obtain a reduction of rent, or to quit his employment.
