Such slight observations, however, upon the prices either of corn or of other commodities, would not probably have misled so many intelligent authors, had they not been influenced at the same time by the popular notion, that as the quantity of silver naturally increases in every country with the increase of wealth, so its value diminishes as its quantity increases. This notion, however, seems to be altogether groundless.
The quantity of the precious metals may increase in any country from two different causes; either, first, from the increased abundance of the mines which supply it; or, secondly, from the increased wealth of the people, from the increased produce of their annual labour. The first of these causes is no doubt necessarily connected with the diminution of the value of the precious metals; but the second is not.
When more abundant mines are discovered, a greater quantity of the precious metals is brought to market; and the quantity of the necessaries and conveniencies of life for which they must be exchanged being the same as before, equal quantities of the metals must be exchanged for smaller quantities of commodities. So far, therefore, as the increase of the quantity of the precious metals in any country arises from the increased abundance of the mines, it is necessarily connected with some diminution of their value.
When, on the contrary, the wealth of any country increases, when the annual produce of its labour becomes gradually greater and greater, a greater quantity of coin becomes necessary in order to circulate a greater quantity of commodities: and the people, as they can afford it, as they have more commodities to give for it, will naturally purchase a greater and a greater quantity of plate. The quantity of their coin will increase from necessity; the quantity of their plate from vanity and ostentation, or from the same reason that the quantity of fine statues, pictures, and of every other luxury and curiosity, is likely to increase among them. But as statuaries and painters are not likely to be worse rewarded in times of wealth and prosperity, than in times of poverty and depression, so gold and silver are not likely to be worse paid for.
The price of gold and silver, when the accidental discovery of more abundant mines does not keep it down, as it naturally rises with the wealth of every country, so, whatever be the state of the mines, it is at all times naturally higher in a rich than in a poor country. Gold and silver, like all other commodities, naturally seek the market where the best price is given for them, and the best price is commonly given for every thing in the country which can best afford it. Labour, it must be remembered, is the ultimate price which is paid for every thing; and in countries where labour is equally well rewarded, the money price of labour will be in proportion to that of the subsistence of the labourer. But gold and silver will naturally exchange for a greater quantity of subsistence in a rich than in a poor country; in a country which abounds with subsistence, than in one which is but indifferently supplied with it. If the two countries are at a great distance, the difference may be very great; because, though the metals naturally fly from the worse to the better market, yet it may be difficult to transport them in such quantities as to bring their price nearly to a level in both. If the countries are near, the difference will be smaller, and may sometimes be scarce perceptible; because in this case the transportation will be easy. China is a much richer country than any part of Europe, and the difference between the price of subsistence in China and in Europe is very great. Rice in China is much cheaper than wheat is any where in Europe. England is a much richer country than Scotland, but the difference between the money price of corn in those two countries is much smaller, and is but just perceptible. In proportion to the quantity or measure, Scotch corn generally appears to be a good deal cheaper than English; but, in proportion to its quality, it is certainly somewhat dearer. Scotland receives almost every year very large supplies from England, and every commodity must commonly be somewhat dearer in the country to which it is brought than in that from which it comes. English corn, therefore, must be dearer in Scotland than in England; and yet in proportion to its quality, or to the quantity and goodness of the flour or meal which can be made from it, it cannot commonly be sold higher there than the Scotch corn which comes to market in competition with it.
The difference between the money price of labour in China and in Europe, is still greater than that between the money price of subsistence; because the real recompence of labour is higher in Europe than in China, the greater part of Europe being in an improving state, while China seems to be standing still. The money price of labour is lower in Scotland than in England, because the real recompence of labour is much lower: Scotland, though advancing to greater wealth, advances much more slowly than England. The frequency of emigration from Scotland, and the rarity of it from England, sufficiently prove that the demand for labour is very different in the two countries. The proportion between the real recompence of labour in different countries, it must be remembered, is naturally regulated, not by their actual wealth or poverty, but by their advancing, stationary, or declining condition.
Gold and silver, as they are naturally of the greatest value among the richest, so they are naturally of the least value among the poorest nations. Among savages, the poorest of all nations, they are scarce of any value.
In great towns, corn is always dearer than in remote parts of the country. This, however, is the effect, not of the real cheapness of silver, but of the real dearness of corn. It does not cost less labour to bring silver to the great town than to the remote parts of the country; but it costs a great deal more to bring corn.
In some very rich and commercial countries, such as Holland and the territory of Genoa, corn is dear for the same reason that it is dear in great towns. They do not produce enough to maintain their inhabitants. They are rich in the industry and skill of their artificers and manufacturers, in every sort of machinery which can facilitate and abridge labour; in shipping, and in all the other instruments and means of carriage and commerce: but they are poor in corn, which, as it must be brought to them from distant countries, must, by an addition to its price, pay for the carriage from those countries. It does not cost less labour to bring silver to Amsterdam than to Dantzic; but it costs a great deal more to bring corn. The real cost of silver must be nearly the same in both places; but that of corn must be very different. Diminish the real opulence either of Holland or of the territory of Genoa, while the number of their inhabitants remains the same; diminish their power of supplying themselves from distant countries; and the price of corn, instead of sinking with that diminution in the quantity of their silver, which must necessarily accompany this declension, either as its cause or as its effect, will rise to the price of a famine. When we are in want of necessaries, we must part with all superfluities, of which the value, as it rises in times of opulence and prosperity, so it sinks in times of poverty and distress. It is otherwise with necessaries. Their real price, the quantity of labour which they can purchase or command, rises in times of poverty and distress, and sinks in times of opulence and prosperity, which are always times of great abundance; for they could not otherwise be times of opulence and prosperity. Corn is a necessary, silver is only a superfluity.
Whatever, therefore, may have been the increase in the quantity of the precious metals, which, during the period between the middle of the fourteenth and that of the sixteenth century, arose from the increase of wealth and improvement, it could have no tendency to diminish their value, either in Great Britain, or in my other part of Europe. If those who have collected the prices of things in ancient times, therefore, had, during this period, no reason to infer the diminution of the value of silver from any observations which they had made upon the prices either of corn, or of other commodities, they had still less reason to infer it from any supposed increase of wealth and improvement.
