CHAPTER XVIII.

VALUE AND RICHES, THEIR DISTINCTIVE PROPERTIES.

"A man is rich or poor," says Adam Smith, "according to the degree in which he can afford to enjoy the necessaries, conveniences, and amusements of human life."

Value then essentially differs from riches, for value depends not on abundance, but on the difficulty or facility of production. The labour of a million of men in manufactures, will always produce the same value, but will not always produce the same riches. By the invention of machinery, by improvements in skill, by a better division of labour, or by the discovery of new markets, where more advantageous exchanges may be made, a million of men may produce double, or treble the amount of riches, of "necessaries, conveniences, and amusements," in one state of society, that they could produce in another, but they will not on that account add any thing to value; for every thing rises or falls in value, in proportion to the facility or difficulty of producing it, or in other words, in proportion to the quantity of labour employed on its production. Suppose with a given capital, the labour of a certain number of men produced 1000 pair of stockings, and that by inventions in machinery, the same number of men can produce 2000 pair, or that they can continue to produce 1000 pair, and can produce besides 500 hats; then the value of the 2000 pair of stockings; or of the 1000 pair of stockings, and 500 hats, will be neither more nor less than that of the 1000 pair of stockings before the introduction of machinery; for they will be the produce of the same quantity of labour. But the value of the general mass of commodities will nevertheless be diminished; for although the value of the increased quantity produced in consequence of the improvement will be the same exactly as the value would have been of the less quantity that would have been produced, had no improvement taken place, an effect is also produced on the portion of goods still unconsumed, which were manufactured previously to the improvement; the value of those goods will be reduced, inasmuch as they must fall to the level, quantity for quantity, of the goods produced under all the advantages of the improvement: and the society will, notwithstanding the increased quantity of its commodities, notwithstanding its augmented riches, and its augmented means of enjoyment, have a less amount of value. By constantly increasing the facility of production, we constantly diminish the value of some of the commodities before produced, though by the same means we not only add to the national riches, but also to the power of future production. Many of the errors in political economy have arisen from errors on this subject, from considering an increase of riches, and an increase of value, as meaning the same thing, and from unfounded notions as to what constituted a standard measure of value. One man considers money as a standard of value, and a nation grows richer or poorer, according to him, in proportion as its commodities of all kinds can exchange for more or less money. Others represent money as a very convenient medium for the purpose of barter, but not as a proper measure by which to estimate the value of other things: the real measure of value according to them is corn,[26] and a country is rich or poor, according as its commodities will exchange for more or less corn. There are others again, who consider a country rich or poor, according to the quantity of labour that it can purchase.[27] But why should gold, or corn, or labour, be the standard measure of value, more than coals or iron?—more than cloth, soap, candles, and the other necessaries of the labourer?—why, in short, should any commodity, or all commodities together, be the standard, when such a standard is itself subject to fluctuations in value? Corn, as well as gold, may from difficulty or facility of production, vary 10, 20, or 30 per cent., relatively to other things; why should we always say, that it is those other things which have varied, and not the corn? That commodity is alone invariable, which at all times requires the same sacrifice of toil and labour to produce it. Of such a commodity we have no knowledge, but we may hypothetically argue and speak about it, as if we had; and may improve our knowledge of the science, by shewing distinctly the absolute inapplicability of all the standards which have been hitherto adopted. But supposing either of these to be a correct standard of value, still it would not be a standard of riches, for riches do not depend on value. A man is rich or poor, according to the abundance of necessaries and luxuries, which he can command; and whether the exchangeable value of these for money, for corn, or for labour, be high or low, they will equally contribute to the enjoyment of their possessor. It is through confounding the ideas of value and wealth, or riches, that it has been asserted, that by diminishing the quantity of commodities, that is to say, of the necessaries, conveniences, and enjoyments of human life, riches may be increased. If value were the measure of riches this could not be denied, because by scarcity the value of commodities is raised; but if Adam Smith be correct, if riches consist in necessaries and enjoyments, then they cannot be increased by a diminution of quantity.

It is true, that the man in possession of a scarce commodity is richer, if by means of it he can command more of the necessaries and enjoyments of human life; but as the general stock out of which each man's riches are drawn, is diminished in quantity, by all that any individual takes from it, other men's shares must necessarily be reduced in proportion as this favoured individual is able to appropriate a greater quantity to himself.

Let water become scarce, says Lord Lauderdale, and be exclusively possessed by an individual, and you will increase his riches, because water will then have value; and if wealth be the aggregate of individual riches, you will by the same means also increase wealth. You undoubtedly will increase the riches of this individual, but inasmuch as the farmer must sell a part of his corn, the shoemaker a part of his shoes, and all men give up a portion of their possessions for the sole purpose of supplying themselves with water, which they before had for nothing, they are poorer by the whole quantity of commodities which they are obliged to devote to this purpose, and the proprietor of water is benefited precisely by the amount of their loss. The same quantity of water, and the same quantity of commodities, are enjoyed by the whole society, but they are differently distributed. This is however supposing rather a monopoly of water than a scarcity of it. If it should be scarce, then the riches of the country and of individuals would be actually diminished, inasmuch as it would be deprived of a portion of one of its enjoyments. The farmer would not only have less corn to exchange for the other commodities which might be necessary or desirable to him, but he and every other individual would be abridged in the enjoyment of one of the most essential of their comforts. Not only would there be a different distribution of riches, but an actual loss of wealth.

It may be said then of two countries possessing precisely the same quantity of all the necessaries and comforts of life, that they are equally rich, but the value of their respective riches would depend on the comparative facility or difficulty with which they were produced. For if an improved piece of machinery should enable us to make two pair of stockings, instead of one, without additional labour, double the quantity would be given in exchange for a yard of cloth. If a similar improvement be made in the manufacture of cloth, stockings and cloth will exchange in the same proportions as before, but they will both have fallen in value; for in exchanging them for hats, for gold, or other commodities in general, twice the former quantity must be given. Extend the improvement to the production of gold, and every other commodity; and they will all regain their former proportions. There will be double the quantity of commodities annually produced in the country, and therefore the wealth of the country will be doubled, but this wealth will not have increased in value.

Although Adam Smith has given the correct description of riches, which I have more than once noticed, he afterwards explains them differently, and says, "that a man must be rich or poor according to the quantity of labour which he can afford to purchase." Now this description differs essentially from the other, and is certainly incorrect; for suppose the mines were to become more productive, so that gold and silver fell in value, from the greater facility of their production; or that velvets were to be manufactured with so much less labour than before, that they fell to half their former value; the riches of all those who purchased those commodities would be increased: one man might increase the quantity of his plate, another might buy double the quantity of velvet; but with the possession of this additional plate, and velvet, they could employ no more labour than before; because as the exchangeable value of velvet and of plate would be lowered, they must part with proportionally more of these species of riches to purchase a day's labour. Riches then cannot be estimated by the quantity of labour which they can purchase.

From what has been said, it will be seen that the wealth of a country may be increased in two ways: it may be increased by employing a greater portion of revenue in the maintenance of productive labour,—which will not only add to the quantity, but to the value of the mass of commodities; or it may be increased, without employing any additional quantity of labour, by making the same quantity more productive,—which will add to the abundance, but not to the value of commodities.
