If direct taxes upon the wages of labour have not always occasioned a proportionable rise in those wages, it is because they have generally occasioned a considerable fall in the demand for labour. The declension of industry, the decrease of employment for the poor, the diminution of the annual produce of the land and labour of the country, have generally been the effects of such taxes. In consequence of them, however, the price of labour must always be higher than it otherwise would have been in the actual state of the demand: and this enhancement of price, together with the profit of those who advance it, must always be finally paid by the landlords and consumers.

A tax upon the wages of country labour does not raise the price of the rude produce of land in proportion to the tax, for the same reason that a tax upon the farmer's profit does not raise that price in that proportion.

Absurd and destructive as such taxes are, however, they take place in many countries. In France that part of the taille which is charged upon the industry of workmen and day-labourers in country villages is properly a tax of this kind. Their wages are computed according to the common rate of the district in which they reside, and that they may be as little liable as possible to any overcharge, their yearly gains are estimated at no more than two hundred working days in the year. The tax of each individual is varied from year to year according to different circumstances, of which the collector or the commissary whom the intendant appoints to assist him are the judges. In Bohemia, in consequence of the alteration in the system of finances which was begun in 1748, a very heavy tax is imposed upon the industry of artificers. They are divided into four classes. The highest class pay a hundred florins a year which, at two-and-twenty pence halfpenny a florin, amounts to L9 7s. 6d. The second class are taxed at seventy; the third at fifty; and the fourth, comprehending artificers in villages, and the lowest class of those in towns, at twenty-five florins.

The recompense of ingenious artists and of men of liberal professions, I have endeavoured to show in the first book, necessarily keeps a certain proportion to the emoluments of inferior trades. A tax upon this recompense, therefore, could have no other effect than to raise it somewhat higher than in proportion to the tax. If it did not rise in this manner, the ingenious arts and the liberal professions, being no longer upon a level with other trades, would be so much deserted that they would soon return to that level.

The emoluments of offices are not, like those of trades and professions, regulated by the free competition of the market, and do not, therefore, always bear a just proportion to what the nature of the employment requires. They are, perhaps, in most countries, higher than it requires; the persons who have the administration of government being generally disposed to reward both themselves and their immediate dependants rather more than enough. The emoluments of offices, therefore, can in most cases very well bear to be taxed. The persons, besides, who enjoy public offices, especially the more lucrative, are in all countries the objects of general envy, and a tax upon their emoluments, even though it should be somewhat higher than upon any other sort of revenue, is always a very popular tax. In England, for example, when by the land-tax every other sort of revenue was supposed to be assessed at four shillings in the pound, it was very popular to lay a real tax of five shillings and sixpence in the pound upon the salaries of offices which exceeded a hundred pounds a year, the pensions of the younger branches of the royal family, the pay of the officers of the army and navy, and a few others less obnoxious to envy excepted. There are in England no other direct taxes upon the wages of labour.

Article IV: Taxes which, it is intended, should fall indifferently upon every different Species of Revenue

The taxes which, it is intended, should fall indifferently upon every different species of revenue, are capitation taxes, and taxes upon consumable commodities. These must be paid indifferently from whatever revenue the contributors may possess; from the rent of their land, from the profits of their stock, or from the wages of their labour.

Capitation Taxes

Capitation taxes, if it is attempted to proportion them to the fortune or revenue of each contributor, become altogether arbitrary. The state of a man's fortune varies from day to day, and without an inquisition more intolerable than any tax, and renewed at least once every year, can only be guessed at. His assessment, therefore, must in most cases depend upon the good or bad humour of his assessors, and must, therefore, be altogether arbitrary and uncertain. Capitation taxes, if they are proportioned not to the supposed fortune, but to the rank of each contributor, become altogether unequal, the degrees of fortune being frequently unequal in the same degree of rank.

Such taxes, therefore, if it is attempted to render them equal, become altogether arbitrary and uncertain, and if it is attempted to render them certain and not arbitrary, become altogether unequal. Let the tax be light or heavy, uncertainty is always a great grievance. In a light tax a considerable degree of inequality may be supported; in a heavy one it is altogether intolerable.

In the different poll-taxes which took place in England during the reign of William III the contributors were, the greater part of them, assessed according to the degree of their rank; as dukes, marquisses, earls, viscounts, barons, esquires, gentlemen, the eldest and youngest sons of peers, etc. All shopkeepers and tradesmen worth more than three hundred pounds, that is, the better sort of them, were subject to the same assessment, how great soever might be the difference in their fortunes. Their rank was more considered than their fortune. Several of those who in the first poll-tax were rated according to their supposed fortune were afterwards rated according to their rank. Serjeants, attorneys, and proctors at law, who in the first poll-tax were assessed at three shillings in the pound of their supposed income, were afterwards assessed as gentlemen. In the assessment of a tax which was not very heavy, a considerable degree of inequality had been found less insupportable than any degree of uncertainty.

In the capitation which has been levied in France without any interruption since the beginning of the present century, the highest orders of people are rated according to their rank by an invariable tariff; the lower orders of people, according to what is supposed to be their fortune, by an assessment which varies from year to year. The officers of the king's court, the judges and other officers in the superior courts of justice, the officers of the troops, etc., are assessed in the first manner. The inferior ranks of people in the provinces are assessed in the second. In France the great easily submit to a considerable degree of inequality in a tax which, so far as it affects them, is not a very heavy one, but could not brook the arbitrary assessment of an intendant. The inferior ranks of people must, in that country, suffer patiently the usage which their superiors think proper to give them.

In England the different poll-taxes never produced the sum which had been expected from them, or which, it was supposed, they might have produced, had they been exactly levied. In France the capitation always produces the sum expected from it. The mild government of England, when it assessed the different ranks of people to the poll-tax, contented itself with what that assessment happened to produce, and required no compensation for the loss which the state might sustain either by those who could not pay, or by those who would not pay (for there were many such), and who, by the indulgent execution of the law, were not forced to pay. The more severe government of France assesses upon each generality a certain sum, which the intendant must find as he can. If any province complains of being assessed too high, it may, in the assessment of next year, obtain an abatement proportioned to the overcharge of the year before. But it must pay in the meantime. The intendant, in order to be sure of finding the sum assessed upon his generality, was empowered to assess it in a larger sum that the failure or inability of some of the contributors might be compensated by the overcharge of the rest, and till 1765 the fixation of this surplus assessment was left altogether to his discretion. In that year, indeed, the council assumed this power to itself. In the capitation of the provinces, it is observed by the perfectly well-informed author of the Memoires upon the impositions in France, the proportion which falls upon the nobility, and upon those whose privileges exempt them from the taille, is the least considerable. The largest falls upon those subject to the taille, who are assessed to the capitation at so much a pound of what they pay to that other tax.

Capitation taxes, so far as they are levied upon the lower ranks of people, are direct taxes upon the wages of labour, and are attended with all the inconveniences of such taxes.

Capitation taxes are levied at little expense, and, where they are rigorously exacted, afford a very sure revenue to the state. It is upon this account that in countries where the ease, comfort, and security of the inferior ranks of people are little attended to, capitation taxes are very common. It is in general, however, but a small part of the public revenue which, in a great empire, has ever been drawn from such taxes, and the greatest sum which they have ever afforded might always have been found in some other way much more convenient to the people.

Taxes upon Consumable Commodities

The impossibility of taxing the people, in proportion to their revenue, by any capitation, seems to have given occasion to the invention of taxes upon consumable commodities. The state, not knowing how to tax, directly and proportionably, the revenue of its subjects, endeavours to tax it indirectly by taxing their expense, which, it is supposed, will in most cases be nearly in proportion to their revenue. Their expense is taxed by taxing the consumable commodities upon which it is laid out. Consumable commodities are either necessaries or luxuries.

By necessaries I understand not only the commodities which are indispensably necessary for the support of life, but whatever the custom of the country renders it indecent for creditable people, even of the lowest order, to be without. A linen shirt, for example, is, strictly speaking, not a necessary of life. The Greeks and Romans lived, I suppose, very comfortably though they had no linen. But in the present times, through the greater part of Europe, a creditable day-labourer would be ashamed to appear in public without a linen shirt, the want of which would be supposed to denote that disgraceful degree of poverty which, it is presumed, nobody can well fall into without extreme bad conduct. Custom, in the same manner, has rendered leather shoes a necessary of life in England. The poorest creditable person of either sex would be ashamed to appear in public without them. In Scotland, custom has rendered them a necessary of life to the lowest order of men; but not to the same order of women, who may, without any discredit, walk about barefooted. In France they are necessaries neither to men nor to women, the lowest rank of both sexes appearing there publicly, without any discredit, sometimes in wooden shoes, and sometimes barefooted. Under necessaries, therefore, I comprehend not only those things which nature, but those things which the established rules of decency have rendered necessary to the lowest rank of people. All other things I call luxuries, without meaning by this appellation to throw the smallest degree of reproach upon the temperate use of them. Beer and ale, for example, in Great Britain, and wine, even in the wine countries, I call luxuries. A man of any rank may, without any reproach, abstain totally from tasting such liquors. Nature does not render them necessary for the support of life, and custom nowhere renders it indecent to live without them.

As the wages of labour are everywhere regulated, partly by the demand for it, and partly by the average price of the necessary articles of subsistence, whatever raises this average price must necessarily raise those wages so that the labourer may still be able to purchase that quantity of those necessary articles which the state of the demand for labour, whether increasing, stationary, or declining, requires that he should have. A tax upon those articles necessarily raises their price somewhat higher than the amount of the tax, because the dealer, who advances the tax, must generally get it back with a profit. Such a tax must, therefore, occasion a rise in the wages of labour proportionable to this rise of price.

It is thus that a tax upon the necessaries of life operates exactly in the same manner as a direct tax upon the wages of labour. The labourer, though he may pay it out of his hand, cannot, for any considerable time at least, be properly said even to advance it. It must always in the long-run be advanced to him by his immediate employer in the advanced rate of his wages. His employer, if he is a manufacturer, will charge upon the price of his goods this rise of wages, together with a profit; so that the final payment of the tax, together with this overcharge, will fall upon the consumer. If his employer is a farmer, the final payment, together with a like overcharge, will fall upon the rent of the landlord.

It is otherwise with taxes upon what I call luxuries, even upon those of the poor. The rise in the price of the taxed commodities will not necessarily occasion any rise in the wages of labour. A tax upon tobacco, for example, though a luxury of the poor as well as of the rich, will not raise wages. Though it is taxed in England at three times, and in France at fifteen times its original price, those high duties seem to have no effect upon the wages of labour. The same thing may be said of the taxes upon tea and sugar, which in England and Holland have become luxuries of the lowest ranks of people, and of those upon chocolate, which in Spain is said to have become so. The different taxes which in Great Britain have in the course of the present century been imposed upon spirituous liquors are not supposed to have had any effect upon the wages of labour. The rise in the price of porter, occasioned by an additional tax of three shillings upon the barrel of strong beer, has not raised the wages of common labour in London. These were about eighteen pence and twenty pence a day before the tax, and they are not more now.
