Putting all these considerations carefully together, we shall find that, in order to levy taxes in a truly equitable and proportionate manner, the imposition ought not to be in simple ratio to the property of the contributors, but in compound ratio to the difference of their conditions and the superfluity of their possessions. This very important and difficult operation is daily made by numbers of honest clerks, who know their arithmetic; but a Plato or a Montesquieu would not venture to undertake it without the greatest diffidence, or without praying to Heaven for understanding and integrity.

Another disadvantage of personal taxes is that they may be too much felt or raised with too great severity. This, however, does not prevent them from being frequently evaded; for it is much easier for persons to escape a tax than for their possessions.

Of all impositions, that on land, or real taxation, has always been regarded as most advantageous in countries where more attention is paid to what the tax will produce, and to the certainty of recovering the product, than to securing the least discomfort for the people. It has been even maintained that it is necessary to burden the peasant in order to rouse him from indolence, and that he would never work if he had no taxes to pay. But in all countries experience confutes this ridiculous notion. In England and Holland the farmer pays very little, and in China nothing: yet these are the countries in which the land is best cultivated. On the other hand, in those countries where the husbandman is taxed in proportion to the produce of his lands, he leaves them uncultivated, or reaps just as much from them as suffices for bare subsistence. For to him who loses the fruit of his labour, it is some gain to do nothing. To lay a tax on industry is a very singular expedient for banishing idleness.

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.

It is further to be noticed that the resources of commerce and industry are so far from rendering the tax more supportable through abundance of money, that they only render it more burdensome. I shall not insist on what is very evident; i.e. that, although a greater or less quantity of money in a State may give it the greater or less credit in the eye of the foreigner, it makes not the least difference to the real fortune of the citizens, and does not make their condition any more or less comfortable. But I must make these two important remarks: first, unless a State possesses superfluous commodities, and abundance of money results from foreign trade, only trading cities are sensible of the abundance; while the peasant only becomes relatively poorer. Secondly, as the price of everything is enhanced by the increase of money, taxes also must be proportionately increased; so that the farmer will find himself still more burdened without having more resources.

It ought to be observed that the tax on land is a real duty on the produce. It is universally agreed, however, that nothing is so dangerous as a tax on corn paid by the purchaser: but how comes it we do not see that it is a hundred times worse when the duty is paid by the cultivator himself? Is not this an attack on the substance of the State at its very source? Is it not the directest possible method of depopulating a country, and therefore in the end ruining it? For the worst kind of scarcity a nation can suffer from is lack of inhabitants.

Only the real statesman can rise, in imposing taxes, above the mere financial object: he alone can transform heavy burdens into useful regulations, and make the people even doubtful whether such establishments were not calculated rather for the good of the nation in general, than merely for the raising of money.

Duties on the importation of foreign commodities, of which the natives are fond, without the country standing in need of them; on the exportation of those of the growth of the country which are not too plentiful, and which foreigners cannot do without; on the productions of frivolous and all too lucrative arts; on the importation of all pure luxuries; and in general on all objects of luxury; will answer the two-fold end in view. It is by such taxes, indeed, by which the poor are eased, and the burdens thrown on the rich, that it is possible to prevent the continual increase of inequality of fortune; the subjection of such a multitude of artisans and useless servants to the rich, the multiplication of idle persons in our cities, and the depopulation of the country-side.
