The error of Adam Smith proceeds in the first place from supposing, that all taxes paid by the farmer must necessarily fall on the landlord, in the shape of a deduction from rent. On this subject I have explained myself most fully, and I trust that it has been shewn, to the satisfaction of the reader, that since much capital is employed on the land which pays no rent, and since it is the result obtained by this capital which regulates the price of raw produce, no deduction can be made from rent; and consequently either no remuneration will be made to the farmer for a tax on wages, or if made, it must be made by an addition to the price of raw produce.
If taxes press unequally on the farmer, he will be enabled to raise the price of raw produce, to place himself on a level with those who carry on other trades; but a tax on wages, which would not affect him more than it would affect any other trade, could not be removed or compensated by a high price of raw produce; for, the same reason which should induce him to raise the price of corn, namely, to remunerate himself for the tax, would induce the clothier to raise the price of cloth, the shoemaker, hatter, and upholsterer, to raise the price of shoes, hats, and furniture.
If they could all raise the price of their goods, so as to remunerate themselves, with a profit, for the tax; as they are all consumers of each other's commodities, it is obvious that the tax could never be paid; for who would be the contributors if all were compensated?
I hope then that I have succeeded in shewing, that any tax which shall have the effect of raising wages, will be paid by a diminution of profits, and therefore that a tax on wages is in fact a tax on profits.
This principle of the division of the produce of labour and capital between wages and profits, which I have attempted to establish, appears to me so certain, that excepting in the immediate effects, I should think it of little importance whether the profits of stock, or the wages of labour, were taxed. By taxing the profits of stock, you would probably alter the rate at which the funds for the maintenance of labour increase, and wages would be disproportioned to the state of that fund, by being too high. By taxing wages, the reward paid to the labourer would also be disproportioned to the state of that fund, by being too low. In the one case by a fall, and in the other by a rise in money wages, the natural equilibrium between profits and wages would be restored. A tax on wages then does not fall on the landlord, but it falls on the profits of stock: it does not "entitle and oblige the master manufacturer to charge it with a profit on the prices of his goods," for he will be unable to increase their price, and therefore he must himself wholly and without compensation pay such a tax.[16]
If the effect of taxes on wages be such as I have described, they do not merit the censure cast upon them by Dr. Smith. He observes of such taxes, "These, and some other taxes of the same kind, by raising the price of labour, are said to have ruined the greater part of the manufactures of Holland. Similar taxes, though not quite so heavy, take place in the Milanese, in the states of Genoa, in the duchy of Modena, in the duchies of Parma, Placentia, and Guastalla, and in the ecclesiastical states. A French author of some note, has proposed to reform the finances of his country, by substituting in the room of other taxes, this most ruinous of all taxes. 'There is nothing so absurd,' says Cicero, 'which has not sometimes been asserted by some philosophers.'" And in another place he says: "taxes upon necessaries, by raising the wages of labour, necessarily tend to raise the price of all manufactures, and consequently to diminish the extent of their sale and consumption." They would not merit this censure; even if Dr. Smith's principle were correct that such taxes would enhance the prices of manufactured commodities; for such an effect could be only temporary, and would subject us to no disadvantage in our foreign trade. If any cause should raise the price of a few manufactured commodities, it would prevent or check their exportation; but if the same cause operated generally on all, the effect would be merely nominal, and would neither interfere with their relative value, nor in any degree diminish the stimulus to a trade of barter; which all commerce, both foreign and domestic, really is.
I have already attempted to shew, that when any cause raises the prices of all commodities in general, the effects are nearly similar to a fall in the value of money. If money falls in value, all commodities rise in price; and if the effect is confined to one country, it will affect its foreign commerce in the same way as a high price of commodities caused by general taxation; and therefore in examining the effects of a low value of money confined to one country, we are also examining the effects of a high price of commodities confined to one country. Indeed Adam Smith was fully aware of the resemblance between these two cases, and consistently maintained that the low value of money, or, as he calls it, of silver in Spain, in consequence of the prohibition against its exportation, was very highly prejudicial to the manufactures and foreign commerce of Spain. "But that degradation in the value of silver, which being the effect either of the peculiar situation, or of the political institutions of a particular country, takes place only in that country, is a matter of very great consequence, which, far from tending to make any body really richer, tends to make every body really poorer. The rise in the money price of all commodities, which is in this case peculiar to that county, tends to discourage more or less every sort of industry which is carried on within it, and to enable foreign nations, by furnishing almost all sorts of goods for a smaller quantity of silver than its own workmen can afford to do, to undersell them not only in the foreign, but even in the home market." Vol. ii. page 278.
One, and I think the only one of the disadvantages of a low value of silver in a country, proceeding from a forced abundance, has been ably explained by Dr. Smith. If the trade in gold and silver were free, "the gold and silver which would go abroad, would not go abroad for nothing, but would bring back an equal value of goods of some kind or another. Those goods too would not be all matters of mere luxury and expense, to be consumed by idle people, who produce nothing in return for their consumption. As the real wealth and revenue of idle people would not be augmented by this extraordinary exportation of gold and silver, so would neither their consumption be augmented by it. Those goods would, probably the greater part of them, and certainly some part of them, consist in materials, tools, and provisions, for the employment and maintenance of industrious people, who would reproduce with a profit, the full value of their consumption. A part of the dead stock of the society would thus be turned into active stock, and would put into motion a greater quantity of industry than had been employed before."
By not allowing a free trade in the precious metals when the prices of commodities are raised, either by taxation, or by the influx of the precious metals, you prevent a part of the dead stock of the society from being turned into active stock—you prevent a greater quantity of industry from being employed. But this is the whole amount of the evil; an evil never felt by those countries where the exportation of silver is either allowed or connived at.
The exchanges between countries are at par only, whilst they have precisely that quantity of currency which in the actual situation of things they should have to carry on the circulation of their commodities. If the trade in the precious metals were perfectly free, and money could be exported without any expense whatever, the exchanges could be no otherwise in every country than at par. If the trade in the precious metals were perfectly free, if they were generally used in circulation, even with the expenses of transporting them, the exchange could never in any of them deviate more from par, than by these expenses. These principles I believe are now no where disputed. If a country used paper money not exchangeable for specie, and therefore not regulated by any fixed standard, the exchanges in that country might deviate as much from par, as its money might be multiplied beyond that quantity which would have been allotted to it by general commerce, if the trade in money had been free, and the precious metals had been used, either for money, or for the standard of money.
