Taxes on land or corn, especially when they are excessive, lead to two results so fatal in their effect that they cannot but depopulate and ruin, in the long run, all countries in which they are established. The first of these arises from the defective circulation of specie; for industry and commerce draw all the money from the country into the capitals: and as the tax destroys the proportion there might otherwise be between the needs of the husbandman and the price of his corn, money is always leaving and never returning. Thus the richer the city the poorer the country. The product of the taxes passes from the hands of the Prince or his financial officers into those of artists and traders; and the husbandman, who receives, only the smallest part of it, is at length exhausted by paying always the same, and receiving constantly less. How could a human body subsist if it had veins and no arteries, or if its arteries conveyed the blood only within four inches of the heart? Chardin tells us that in Persia the royal dues on commodities are paid in kind: this custom, which, Herodotus informs us, prevailed long ago in the same country down to the time of Darius, might prevent the evil of which I have been speaking. But unless Intendants, Directors, Commissioners and Warehousemen in Persia are a different kind of people from what they are elsewhere, I can hardly believe that the smallest part of this produce ever reaches the king, or that the corn is not spoilt in every granary, and the greater part of the warehouses not consumed by fire. The second evil effect arises from an apparent advantage, which aggravates the evil before it can be perceived. That is that corn is a commodity whose price is not enhanced by taxes in the country producing it, and which, in spite of its absolute necessity, may be diminished in quantity without the price being increased. Hence, many people die of hunger, although corn remains cheap, and the husbandman bears the whole charge of a tax, for which he cannot indemnify himself by the price of his corn. It must be observed that we ought not to reason about a land-tax in the same manner as about duties laid on various kinds of merchandise; for the effect of such duties is to raise the price, and they are paid by the buyers rather than the sellers. For these duties, however heavy, are still voluntary, and are paid by the merchant only in proportion to the quantity he buys; and as he buys only in proportion to his sale, he himself gives the law its particular application; but the farmer who is obliged to pay his rent at stated times, whether he sells or not, cannot wait till he can get his own price for his commodity: even if he is not forced to sell for mere subsistence, he must sell to pay the taxes; so that it is frequently the heaviness of the tax that keeps the price of corn low.
