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 inconveniencies 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 indispensibly 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.[70] 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 state of wages. His employer, if he is a manufacturer, will charge upon the price of his goods the 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 spiritous 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 or twenty pence a-day before the tax, and they are not more now.
