The Precious Metals The Best Measure Of Prices.

It is no more possible to find a constant measure of prices than it is to square the circle. (J. B. Say.) If the two magnitudes to be compared are separated from each other in space but not in time, the precious metals constitute not only the best measure of their prices, but also a very good one. But the precious metals are subject to very sensible and accidental variations in price in long periods of time. If, therefore, we would compare sums of money belonging to different times with one another, we must first construct a price-current list of all the more important articles of commerce for the time in question, and in the quantities they are needed in every [pg 386] day life. We would next have to calculate the average of these mean prices, and thus to determine the relative value of the amounts to be estimated.[781] The person who should limit his comparison to a few species of commodities, says von Mangoldt, would lose in exactness what he gained in comprehensibility.

In every such list, the wages of a day would occupy a very important place. The desire of exerting an influence over the lives and actions of other men, and the desire of relatively greater social distinction as compared with the social distinction of others, is very general; and there is scarcely any better evidence that it has been attained than the possession of the power of controlling a large number of days' work. The man who can keep one thousand day laborers is certainly, in a politico-economical [pg 387] sense, an important personage. Besides, the height of day-wages has the most direct influence on the price of many other commodities.[782]

No less important is the price of wheat, or rather of the principal article of food of the people, for the time being, with which the price of inland raw material—in so far as it can be produced from the same soil alternately with wheat—and, in the long run, also the wages of labor, are so essentially connected.[783] The same indispensable necessity of wheat which causes its price to fluctuate so largely from year to year, and from month to month, promotes the uniformity of its average price,[784] when many years are taken into the account.[785][786] [pg 388] (Malthus.) If, by reason of great progress made in the art of agriculture, the cost of the production of wheat should fall to one-half of what it was, a large increase of population would certainly not be delayed long. And so, on the other hand, there would be a decrease of population if, by the destruction of artificial means of irrigation, or other steps in the direction of a retrogressive civilization, the cost of the production of wheat were to be permanently increased.

But even the average price of wheat, during a long series of years, is not entirely invariable. The increasing consumption compels the nation, as a whole, to provide for its requirement of wheat from less fertile sources, which increases its price generally. It is true that the progress of the science of agriculture and of the corn-trade counteract this tendency, retard the advance of the price of wheat, and may, for a time, produce an opposite tendency. It is true, also, that the people are induced by their most general and vital interests to take advantage of this possibility. But spite of the frequency of exceptions to it, the rule remains.[787] If, therefore, we wished to so fix a perpetual annuity that it should always be worth [pg 389] as much money as a certain quantity of wheat had cost, on an average, during the three preceding decades, the thing-value of this annuity would, on the whole, rise with an advance in civilization.[788] To obtain something that would remain the same, it would be necessary to combine wheat with at least one chief commodity, the intrinsic basis of the price of which had a development independent of the price of grain; but the whole to be made payable in money. The precious metals are, in many respects, so diametrically opposed in properties to wheat, in their dispensableness, transportable character and durability, for instance, that these two classes of commodities are best adapted to act as counter-balances to each other.[789]

Section CXXX.

History Of The Prices Of The Chief Wants Of Life.

The higher civilization advances, the dearer all those commodities in the production of which the factor nature with [pg 390] value in exchange predominates are apt to become; and the cheaper, on the other hand, all those in which labor and capital play the principal productive part.[790] This is accounted for, not only by the almost unlimited capacity of labor and capital to be increased, while the natural forces which have value in exchange are susceptible of increase to so small an extent; but also, and especially, because new additions of labor and capital are wont to cause relatively smaller results in the production of raw material, and relatively larger ones in industry and commerce. (§ [33], ff).[791]

Hence, from the relations the prices of the different classes of commodities bear to one another, we may draw important conclusions as to the degree of civilization which a country has attained. The above law also affords an explanation of the fact, that a young nation, which has made no great strides in the way of development, and in which, of course, the production of raw material preponderates, draw their commercial and manufactured necessaries, by way of preference, from [pg 391] precisely the most highly civilized foreign nations. The latter are in a condition, and accustomed, to give the largest quantity and the best quality of manufactured articles for a required quantity of raw material; and, of course, vice versa. Hence, in this intercourse of nations, the most urgent want, and the completest and easiest possibility of satisfying it, meet.[792] Only very highly civilized mother-countries can hold fast to colonial possessions in our day.
