Without calling in question the policy, which dictated this alteration of the tax, I may be permitted to doubt whether it gave any great stimulus to accumulation. If the profits of the fisherman and others engaged in the trade, were doubled in consequence of more fish being consumed, capital and labour must have been withdrawn from other occupations to engage them in this particular trade. But in those occupations capital and labour were productive of profits, which must have been given up when they were withdrawn. The ability of the country to accumulate was only increased by the difference between the profits obtained in the business in which the capital was newly engaged, and those obtained in that from which it was withdrawn.
Whether taxes be taken from revenue or capital, they diminish the taxable commodities of the state. If I cease to expend 100l. on wine, because by paying a tax of that amount I have enabled Government to expend 100l. instead of expending it myself, one hundred pounds worth of goods are necessarily withdrawn from the list of taxable commodities. If the revenue of the individuals of a country be 10 millions, they will have at least 10 millions worth of taxable commodities. If by taxing some, one million be transferred to the disposal of Government, their revenue will still be nominally 10 millions, but they will remain with only nine millions worth of taxable commodities. There are no circumstances under which taxation does not abridge the enjoyments of those on whom the taxes ultimately fall, and no means by which those enjoyments can again be extended, but the accumulation of new revenue.
Taxation can never be so equally applied, as to operate in the same proportion on the value of all commodities, and still to preserve them at the same relative value. It frequently operates very differently from the intention of the legislature, by its indirect effects. We have already seen, that the effect of a direct tax on corn and raw produce, is, if money be also produced in the country, to raise the price of all commodities, in proportion as raw produce enters into their composition, and thereby to destroy the natural relation which previously existed between them. Another indirect effect is, that it raises wages, and lowers the rate of profits; and we have also seen, in another part of this work, that the effect of a rise of wages, and a fall of profits, is to lower the money prices of those commodities which are produced in a greater degree by the employment of fixed capital.
That a commodity when taxed can no longer be so profitably exported, is so well understood, that a drawback is frequently allowed on its exportation, and a duty laid on its importation. If these drawbacks and duties be accurately laid, not only on the commodities themselves, but on all which they may indirectly affect, then indeed there will be no disturbance in the value of the precious metals. Since we could as readily export a commodity after being taxed as before, and since no peculiar facility would be given to importation, the precious metals would not, more than before, enter into the list of exportable commodities.
Of all commodities, none are perhaps so proper for taxation, as those which either by the aid of nature or art, are produced with peculiar facility. With respect to foreign countries, such commodities may be classed under the head of those which are not regulated in their price by the quantity of labour bestowed, but rather by the caprice, the tastes, and the power of the purchasers. If England had more productive tin mines than other countries, or if from superior machinery or fuel she had peculiar facilities in manufacturing cotton goods, the prices of tin, and of cotton goods would still in England be regulated by the comparative quantity of labour and capital required to produce them, and the competition of our merchants would make them very little dearer to the foreign consumer. Our advantage in the production of these commodities might be so decided, that probably they could bear a very great additional price in the foreign market, without very materially diminishing their consumption. This price they never could attain, whilst competition was free at home, by any other means but by a tax on their exportation. This tax would fall wholly on foreign consumers, and part of the expenses of the Government of England would be defrayed, by a tax on the land and labour of other countries. The tax on tea, which at present is paid by the people of England, and goes to aid the expenses of the Government of England, might, if laid in China, on the exportation of the tea, be diverted to the payment of the expenses of the Government of China.
Taxes on luxuries have some advantage over taxes on necessaries. They are generally paid from income, and therefore do not diminish the productive capital of the country. If wine were much raised in price in consequence of taxation, it is probable that a man would rather forego the enjoyments of wine, than make any important encroachments on his capital, to be enabled to purchase it. They are so identified with price, that the contributor is hardly aware that he is paying a tax. But they have also their disadvantages. First, they never reach capital, and on some extraordinary occasions it may be expedient that even capital should contribute towards the public exigencies; and secondly, there is no certainty as to the amount of the tax, for it may not reach even income. A man intent on saving will exempt himself from a tax on wine, by giving up the use of it. The income of the country may be undiminished, and yet the state may be unable to raise a shilling by the tax.
Whatever habit has rendered delightful, will be relinquished with reluctance, and will continue to be consumed notwithstanding a very heavy tax; but this reluctance has its limits, and experience every day demonstrates that an increase in the nominal amount of taxation, often diminishes the produce. One man will continue to drink the same quantity of wine, though the price of every bottle should be raised three shillings, who would yet relinquish the use of wine rather than pay four. Another will be content to pay four, yet refuse to pay five shillings. The same may be said of other taxes on luxuries: many would pay a tax of 5l. for the enjoyment which a horse affords, who would not pay 10l. or 20l. It is not because they cannot pay more, that they give up the use of wine and of horses, but because they will not pay more. Every man has some standard in his own mind by which he estimates the value of his enjoyments, but that standard is as various as the human character. A country whose financial situation has become extremely artificial, by the mischievous policy of accumulating a large national debt, and a consequently enormous taxation, is particularly exposed to the inconvenience attendant on this mode of raising taxes. After visiting with a tax the whole round of luxuries; after laying horses, carriages, wine, servants, and all the other enjoyments of the rich, under contribution; a minister is disposed to conclude that the country is arrived at the maximum of taxation, because by increasing the rate, he cannot increase the amount of any one of these taxes. But in this conclusion he will not be always correct, for it is very possible that such a country could bear a very great addition to its burdens without infringing on the integrity of its capital.
