Will not this principle account for the different effects, which it was remarked were produced on the prices of commodities, from the altered value of money during the Bank-restriction? It was objected to those who contended that the currency was at that period depreciated, from the too great abundance of the paper circulation, that, if that were the fact, all commodities ought to have risen in the same proportion; but it was found that many had varied considerably more than others, and thence it was inferred that the rise of prices was owing to something affecting the value of commodities, and not to any alteration in the value of the currency. It appears however, as we have just seen, that in a country where commodities are taxed, they will not all vary in price in the same proportion, either in consequence of a rise or of a fall in the value of currency.
If the profits of all trades were taxed, excepting the profits of the farmer, all goods would rise in money value, excepting raw produce. The farmer would have the same corn income as before, and would sell his corn also for the same money price; but as he would be obliged to pay an additional price for all the commodities, except corn, which he consumed, it would be to him a tax on expenditure. Nor would he be relieved from this tax by an alteration in the value of money, for an alteration in the value of money might sink all the taxed commodities to their former price, but the untaxed one would sink below its former level; and therefore, though the farmer would purchase his commodities at the same price as before, he would have less money with which to purchase them.
The landlord too would be precisely in the same situation, he would have the same corn, and the same money rent as before, if all commodities rose in price, and money remained at the same value; and he would have the same corn, but a less money rent, if all commodities remained at the same price: so that in either case, though his income were not directly taxed, he would indirectly contribute towards the money raised.
But suppose the profits of the farmer to be also taxed, he then would be in the same situation as other traders; his raw produce would rise, so that he would have the same money revenue, after paying the tax, but he would pay an additional price for all the commodities he consumed, raw produce included.
His landlord however would be differently situated, he would be benefited by the tax on his tenant's profits, as he would be compensated for the additional price at which he would purchase his manufactured commodities, if they rose in price; and he would have the same money revenue, if in consequence of a rise in the value of money, commodities sold at their former price. A tax on the profits of the farmer, is not a tax proportioned to the gross produce of the land, but to its net produce, after the payment of rent, wages, and all other charges. As the cultivators of the different kinds of land, No. 1, 2, and 3, employ precisely the same capitals, they will get precisely the same profits, whatever may be the quantity of gross produce, which one may obtain more than the other; and consequently they will be all taxed alike. Suppose the gross produce of the land of the quality No. 1, to be 180 qrs., that of No. 2, 170 qrs., and of No 3, 160, and each to be taxed 10 quarters, the difference between the produce of No. 1, No. 2, and No. 3, after paying the tax, will be the same as before; for if No. 1 be reduced to 170, No. 2 to 160, and No. 3 to 150 qrs.; the difference between 3 and 1 will be as before, 20 qrs.; and of No. 3 and No. 2, 10 qrs. If after the tax the prices of corn and of every other commodity should remain the same as before, money rent as well as corn rent, would continue unaltered; but if the price of corn, and every other commodity should rise in consequence of the tax, money rent will also rise in the same proportion. If the price of corn were 4l. per quarter, the rent of No. 1 would have been 80l., and that of No. 2, 40l.; but if corn rose ten per cent., or to 4l. 8s., rent would also rise ten per cent., for twenty quarters of corn would then be worth 88l., and ten quarters 44l.; so that in every case the landlord will be unaffected by such a tax. A tax on the profits of stock always leaves corn rent unaltered, and therefore money rent varies with the price of corn; but a tax on raw produce, or tithes, never leaves corn rent unaltered, but generally leaves money rent the same as before. In another part of this work I have observed, that if a land-tax of the same money amount, were laid on every kind of land in cultivation, without any allowance for difference of fertility, it would be very unequal in its operation, as it would be a profit to the landlord of the more fertile lands. It would raise the price of corn in proportion to the burden borne by the farmer of the worst land; but this additional price being obtained for the greater quantity of produce yielded by the better land, farmers of such land would be benefited during their leases, and afterwards, the advantage would go to the landlord in the form of an increase of rent. The effect of an equal tax on the profits of the farmer is precisely the same; it raises the money rent of the landlords, if money retains the same value; but as the profits of all other trades are taxed, as well as those of the farmer, and consequently the prices of all goods, as well as corn, are raised, the landlord loses as much by the increased money price of the goods and corn on which his rent is expended, as he gains by the rise of his rent. If money should rise in value, and all things should, after a tax on the profits of stock, fall to their former prices, rent also would be the same as before. The landlord would receive the same money rent, and would obtain all the commodities on which it was expended at their former price; so that under all circumstances he would continue untaxed.
A tax on the profits of stock would also affect the stockholder, if all commodities were to rise in proportion to the tax; but if from the alteration in the value of money, all commodities were to sink to their former price, the stockholder would pay nothing towards the tax; he would purchase all his commodities at the same price, but would still receive the same money dividend.
If it be agreed, that by taxing the profits of one manufacturer only, the price of his goods would rise, to put him on an equality with all other manufacturers; and that by taxing the profits of two manufacturers, the prices of two descriptions of goods must rise, I do not see how it can be disputed, that by taxing the profits of all manufacturers, the prices of all goods would rise, provided the mine which supplied us with money, were in the country taxed. But as money, or the standard of money, is a commodity imported from abroad, the prices of all goods could not rise; for such an effect could not take place without an additional quantity of money, which could not be obtained in exchange for dear goods, as was shewn in page 108. If however, such a rise could take place, it could not be permanent, for it would have a powerful influence on foreign trade. In return for commodities imported, those dear goods could not be exported, and therefore we should for a time continue to buy, although we ceased to sell; and should export money, or bullion, till the relative prices of commodities were nearly the same as before. It appears to me absolutely certain, that a well regulated tax on profits, would ultimately restore commodities both of home and foreign manufacture, to the same money price which they bore before the tax was imposed.
As taxes on raw produce, tithes, taxes on wages, and on the necessaries of the labourer, will, by raising wages, lower profits, they will all, though not in an equal degree, be attended with the same effects.
The discovery of machinery, which materially improves home manufactures, always tends to raise the relative value of money, and therefore to encourage its importation. All taxation, all increased impediments, either to the manufacturer, or the grower of commodities, tend on the contrary to lower the relative value of money, and therefore to encourage its exportation.
