The Wealth of Nations_ Books 4-5 - Adam Smith [290]
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
