When the water-carrier comes to supply my house, were I to pay him in proportion to the absolute utility of the water, my whole fortune would not be sufficient. But I pay him only for the trouble he has taken. If he requires more, I can get others to furnish it, or finally go and get it myself. The water itself is not the subject of our bargain; but the labor taken to get the water. This point of view is so important, and the consequences that I am going to draw from it so clear, as regards the freedom of international exchanges, that I will still elucidate my idea by a few more examples.
The alimentary substance contained in potatoes does not cost us very dear, because a great deal of it is attainable with little work. We pay more for wheat, because, to produce it Nature requires more labor from man. It is evident that if Nature did for the latter what she does for the former, their prices would tend to the same level. It is impossible that the producer of wheat should permanently gain more than the producer of potatoes. The law of competition cannot allow it.
If by a happy miracle the fertility of all arable lands were to be increased, it would not be the agriculturist, but the consumer, who would profit by this phenomenon; for the result of it would be, abundance and cheapness. There would be less labor incorporated into an acre of grain, and the agriculturist would be therefore obliged to exchange it for a less labor incorporated into some other article. If, on the contrary, the fertility of the soil were suddenly to deteriorate, the share of Nature in production would be less, that of labor greater, and the result would be higher prices. I am right then in saying that it is in consumption, in mankind, that at length all political phenomena find their solution. As long as we fail to follow their effects to this point, and look only at immediate effects, which act but upon individual men or classes of men as producers, we know nothing more of political economy than the quack does of medicine, when, instead of following the effects of a prescription in its action upon the whole system, he satisfies himself with knowing how it affects the palate and the throat.
The tropical regions are very favorable to the production of sugar and coffee; that is to say, Nature does most of the business and leaves but little for labor to accomplish. But who reaps the advantage of this liberality of Nature? Not these regions, for they are forced by competition to receive simply remuneration for their labor. It is mankind who is the gainer; for the result of this liberality is cheapness, and cheapness belongs to the world.
Here in the temperate zone, we find coal and iron ore, on the surface of the soil; we have but to stoop and take them. At first, I grant, the immediate inhabitants profit by this fortunate circumstance. But soon comes competition, and the price of coal and iron falls, until this gift of Nature becomes gratuitous to all, and human labor is only paid according to the general rate of profits.
Thus natural advantages, like improvements in the process of production, are, or have a constant tendency to become, under the law of competition, the common and gratuitous patrimony of consumers, of society, of mankind. Countries therefore which do not enjoy these advantages, must gain by commerce with those which do; because the exchanges of commerce are between labor and labor; subtraction being made of all the natural advantages which are combined with these labors; and it is evidently the most favored countries which can incorporate into a given labor the largest proportion of these natural advantages. Their produce representing less labor, receives less recompense; in other words, is cheaper. If then all the liberality of Nature results in cheapness, it is evidently not the producing, but the consuming country, which profits by her benefits.
Hence we may see the enormous absurdity of the consuming country, which rejects produce precisely because it is cheap. It is as though we should say: "We will have nothing of that which Nature gives you. You ask of us an effort equal to two, in order to furnish ourselves with articles only attainable at home by an effort equal to four. You can do it because with you Nature does half the work. But we will have nothing to do with it; we will wait till your climate, becoming more inclement, forces you to ask of us a labor equal to four, and then we can treat with you upon an equal footing."
A is a favored country; B is maltreated by Nature. Mutual traffic then is advantageous to both, but principally to B, because the exchange is not between utility and utility, but between value and value. Now A furnishes a greater utility in a similar value, because the utility of any article includes at once what Nature and what labor have done; whereas the value of it only corresponds to the portion accomplished by labor. B then makes an entirely advantageous bargain; for by simply paying the producer from A for his labor, it receives in return not only the results of that labor, but in addition there is thrown in whatever may have accrued from the superior bounty of Nature.
We will lay down the general rule.
Traffic is an exchange of values; and as value is reduced by competition to the simple representation of labor, traffic is the exchange of equal labors. Whatever Nature has done towards the production of the articles exchanged, is given on both sides gratuitously; from whence it necessarily follows, that the most advantageous commerce is transacted with those countries which are the most favored by Nature.
