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.

The high price of such commodities does not necessarily diminish the ability of the inferior ranks of people to bring up families. Upon the sober and industrious poor, taxes upon such commodities act as sumptuary laws, and dispose them either to moderate, or to refrain altogether from the use of superfluities which they can no longer easily afford. Their ability to bring up families, in consequence of this forced frugality, instead of being diminished, is frequently, perhaps, increased by the tax. It is the sober and industrious poor who generally bring up the most numerous families, and who principally supply the demand for useful labour. All the poor, indeed, are not sober and industrious, and the dissolute and disorderly might continue to indulge themselves in the use of such commodities after this rise of price in the same manner as before without regarding the distress which this indulgence might bring upon their families. Such disorderly persons, however, seldom rear up numerous families, their children generally perishing from neglect, mismanagement, and the scantiness or unwholesomeness of their food. If by the strength of their constitution they survive the hardships to which the bad conduct of their parents exposes them, yet the example of that bad conduct commonly corrupts their morals, so that, instead of being useful to society by their industry, they become public nuisances by their vices and disorders. Though the advanced price of the luxuries of the poor, therefore, might increase somewhat the distress of such disorderly families, and thereby diminish somewhat their ability to bring up children, it would not probably diminish much the useful population of the country.

Any rise in the average price of necessaries, unless it is compensated by a proportionable rise in the wages of labour, must necessarily diminish more or less the ability of the poor to bring up numerous families, and consequently to supply the demand for useful labour, whatever may be the state of that demand, whether increasing, stationary, or declining, or such as requires an increasing, stationary, or declining population.

Taxes upon luxuries have no tendency to raise the price of any other commodities except that of the commodities taxed. 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. Taxes upon luxuries are finally paid by the consumers of the commodities taxed without any retribution. They fall indifferently upon every species of revenue, the wages of labour, the profits of stock, and the rent of land. Taxes upon necessaries, so far as they affect the labouring poor, are finally paid, partly by landlords in the diminished rent of their lands, and partly by rich consumers, whether landlords or others, in the advanced price of manufactured goods, and always with a considerable overcharge. The advanced price of such manufactures as are real necessaries of life, and are destined for the consumption of the poor, of coarse woollens, for example, must be compensated to the poor by a further advancement of their wages. The middling and superior ranks of people, if they understand their own interest, ought always to oppose all taxes upon the necessaries of life, as well as all direct taxes upon the wages of labour. The final payment of both the one and the other falls altogether upon themselves, and always with a considerable overcharge. They fall heaviest upon the landlords, who always pay in a double capacity; in that of landlords by the reduction of their rent, and in that of rich consumers by the increase of their expense. The observation of Sir Matthew Decker, that certain taxes are, in the price of certain goods, sometimes repeated and accumulated four or five times, is perfectly just with regard to taxes upon the necessaries of life. In the price of leather, for example, you must pay not only for the tax upon the leather of your own shoes, but for a part of that upon those of the shoemaker and the tanner. You must pay, too, for the tax upon the salt, upon the soap, and upon the candles which those workmen consume while employed in your service, and for the tax upon the leather which the salt-maker, the soap-maker, and the candle-maker consume while employed in their service.

In Great Britain, the principal taxes upon the necessaries of life are those upon the four commodities just now mentioned, salt, leather, soap, and candles.

Salt is a very ancient and a very universal subject of taxation. It was taxed among the Romans, and it is so at present in, I believe, every part of Europe. The quantity annually consumed by any individual is so small, and may be purchased so gradually, that nobody, it seems to have been thought, could feel very sensibly even a pretty heavy tax upon it. It is in England taxed at three shillings and fourpence a bushel - about three times the original price of the commodity. In some other countries the tax is still higher. Leather is a real necessary of life. The use of linen renders soap such. In countries where the winter nights are long, candles are a necessary instrument of trade. Leather and soap are in Great Britain taxed at three halfpence a pound, candles at a penny; taxes which, upon the original price of leather, may amount to about eight or ten per cent; upon that of soap to about twenty or five-and-twenty per cent; and upon that of candles to about fourteen or fifteen per cent; taxes which, though lighter than that upon salt, are still very heavy. As all those four commodities are real necessaries of life, such heavy taxes upon them must increase somewhat the expense of the sober and industrious poor, and must consequently raise more or less the wages of their labour.

In a country where the winters are so cold as in Great Britain, fuel is, during that season, in the strictest sense of the word, a necessary of life, not only for the purpose of dressing victuals, but for the comfortable subsistence of many different sorts of workmen who work within doors; and coals are the cheapest of all fuel. The price of fuel has so important an influence upon that of labour that all over Great Britain manufactures have confined themselves principally to the coal countries, other parts of the country, on account of the high price of this necessary article, not being able to work so cheap. In some manufactures, besides, coal is a necessary instrument of trade, as in those of glass, iron, and all other metals. If a bounty could in any case be reasonable, it might perhaps be so upon the transportation of coals from those parts of the country in which they abound to those in which they are wanted. But the legislature, instead of a bounty, has imposed a tax of three shillings and threepence a ton upon coal carried coastways, which upon most sorts of coal is more than sixty per cent of the original price at the coal-pit. Coals carried either by land or by inland navigation pay no duty. Where they are naturally cheap, they are consumed duty free: where they are naturally dear, they are loaded with a heavy duty.

Such taxes, though they raise the price of subsistence, and consequently the wages of labour, yet they afford a considerable revenue to government which it might not be easy to find in any other way. There may, therefore, be good reasons for continuing them. The bounty upon the exportation of corn, so far as it tends in the actual state of tillage to raise the price of that necessary article, produces all the like bad effects, and instead of affording any revenue, frequently occasions a very great expense to government. The high duties upon the importation of foreign corn, which in years of moderate plenty amount to a prohibition, and the absolute prohibition of the importation either of live cattle or of salt provisions, which takes place in the ordinary state of the law, and which, on account of the scarcity, is at present suspended for a limited time with regard to Ireland and the British plantations, have all the bad effects of taxes upon the necessaries of life, and produce no revenue to government. Nothing seems necessary for the repeal of such regulations but to convince the public of the futility of that system in consequence of which they have been established.

Taxes upon the necessaries of life are much higher in many other countries than in Great Britain. Duties upon flour and meal when ground at the mill, and upon bread when baked at the oven, take place in many countries. In Holland the money price of the bread consumed in towns is supposed to be doubled by means of such taxes. In lieu of a part of them, the people who live in the country pay every year so much a head according to the sort of bread they are supposed to consume. Those who consume wheaten bread pay three guilders fifteen stivers - about six shillings and ninepence halfpenny. 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 state. A French author of some note has proposed to reform the finances of his country by substituting in the room of the greater part of other taxes this most ruinous of all taxes. There is nothing so absurd, says Cicero, which has not sometimes been asserted by philosophers.

Taxes upon butchers' meat are still more common than those upon bread. It may indeed be doubted whether butchers' meat is anywhere a necessary of life. Grain and other vegetables, with the help of milk, cheese, and butter, or oil where butter is not to be had, it is known from experience, can, without any butchers' meat, afford the most plentiful, the most wholesome, the most nourishing, and the most invigorating diet. Decency nowhere requires that any man should eat butchers' meat, as it in most places requires that he should wear a linen shirt or a pair of leather shoes.

Consumable commodities, whether necessaries or luxuries, may be taxed in two different ways. The consumer may either pay an annual sum on account of his using or consuming goods of a certain kind, or the goods may be taxed while they remain in the hands of the dealer, and before they are delivered to the consumer. The consumable goods which last a considerable time before they are consumed altogether are most properly taxed in the one way; those of which the consumption is either immediate or more speedy, in the other. The coach-tax and plate-tax are examples of the former method of imposing: the greater part of the other duties of excise and customs, of the latter.

A coach may, with good management, last ten or twelve years. It might be taxed, once for all, before it comes out of the hands of the coachmaker. But it is certainly more convenient for the buyer to pay four pounds a year for the privilege of keeping a coach than to pay all at once forty or forty-eight pounds additional price to the coachmaker, or a sum equivalent to what the tax is likely to cost him during the time he uses the same coach. A service of plate, in the same manner, may last more than a century. It is certainly easier for the consumer to pay five shillings a year for every hundred ounces of plate, near one per cent of the value, than to redeem this long annuity at five-and-twenty or thirty years' purchase, which would enhance the price at least five-and-twenty or thirty per cent. The different taxes which affect houses are certainly more conveniently paid by moderate annual payments than by a heavy tax of equal value upon the first building or sale of the house.

It was the well-known proposal of Sir Matthew Decker that all commodities, even those of which the consumption is either immediate or very speedy, should be taxed in this manner, the dealer advancing nothing, but the consumer paying a certain annual sum for the licence to consume certain goods. The object of his scheme was to promote all the different branches of foreign trade, particularly the carrying trade, by taking away all duties upon importation and exportation, and thereby enabling the merchant to employ his whole capital and credit in the purchase of goods and the freight of ships, no part of either being diverted towards the advancing of taxes. The project, however, of taxing, in this manner, goods of immediate or speedy consumption seems liable to the four following very important objections. First, the tax would be more unequal, or not so well proportioned to the expense and consumption of the different contributors as in the way in which it is commonly imposed. The taxes upon ale, wine, and spirituous liquors, which are advanced by the dealers, are finally paid by the different consumers exactly in proportion to their respective consumption. But if the tax were to be paid by purchasing a licence to drink those liquors, the sober would, in proportion to his consumption, be taxed much more heavily than the drunken consumer. A family which exercised great hospitality would be taxed much more lightly than one who entertained fewer guests. Secondly, this mode of taxation, by paying for an annual, half-yearly, or quarterly licence to consume certain goods, would diminish very much one of the principal conveniences of taxes upon goods of speedy consumption the piecemeal payment. In the price of threepence halfpenny, which is at present paid for a pot of porter, the different taxes upon malt, hops, and beer, together with the extraordinary profit which the brewer charges for having advanced them, may perhaps amount to about three halfpence. If a workman can conveniently spare those three halfpence, he buys a pot of porter. If he cannot, he contents himself with a pint, and, as a penny saved is a penny got, he thus gains a farthing by his temperance. He pays the tax piecemeal as he can afford to pay it, and when he can afford to pay it, and every act of payment is perfectly voluntary, and what he can avoid if he chooses to do so. Thirdly, such taxes would operate less as sumptuary laws. When the licence was once purchased, whether the purchaser drank much or drank little, his tax would be the same. Fourthly, if a workman were to pay all at once, by yearly, half-yearly, or quarterly payments, a tax equal to what he at present pays, with little or no inconveniency, upon all the different pots and pints of porter which he drinks in any such period of time, the sum might frequently distress him very much. This mode of taxation, therefore, it seems evident, could never, without the most grievous oppression, produce a revenue nearly equal to what is derived from the present mode without any oppression. In several countries, however, commodities of an immediate or very speedy consumption are taxed in this manner. In Holland people pay so much a head for a licence to drink tea. I have already mentioned a tax upon bread, which, so far as it is consumed in farm-houses and country villages, is there levied in the same manner.

The duties of excise are imposed briefly upon goods of home produce destined for home consumption. They are imposed only upon a few sorts of goods of the most general use. There can never be any doubt either concerning the goods which are subject to those duties, or concerning the particular duty which each species of goods is subject to. They fall almost altogether upon what I call luxuries, excepting always the four duties above mentioned, upon salt soap, leather, candles, and, perhaps, that upon green glass.

The duties of customs are much more ancient than those of excise. They seem to have been called customs as denoting customary payments which had been in use from time immemorial. They appear to have been originally considered as taxes upon the profits of merchants. During the barbarous times of feudal anarchy, merchants, like all the other inhabitants of burghs, were considered as little better than emancipated bondmen, whose persons were despised, and whose gains were envied. The great nobility, who had consented that the king should tallage the profits of their own tenants, were not unwilling that he should tallage likewise those of an order of men whom it was much less their interest to protect. In those ignorant times it was not understood that the profits of merchants are a subject not taxable directly, or that the final payment of all such taxes must fall, with a considerable overcharge, upon the consumers.

The gains of alien merchants were looked upon more unfavourably than those of English merchants. It was natural, therefore, that those of the former should be taxed more heavily than those of the latter. This distinction between the duties upon aliens and those upon English merchants, which was begun from ignorance, has been continued from the spirit of monopoly, or in order to give our own merchants an advantage both in the home and in the foreign market.

With this distinction, the ancient duties of customs were imposed equally upon all sorts of goods, necessaries as well as luxuries, goods exported as well as goods imported. Why should the dealers in one sort of goods, it seems to have been thought, be more favoured than those in another? or why should the merchant exporter be more favoured than the merchant importer?
