They represented, secondly, that this prohibition could not hinder the exportation of gold and silver, which, on account of the smallness of their bulk in proportion to their value, could easily be smuggled abroad. That this exportation could only be prevented by a proper attention to what they called the balance of trade. That when the country exported to a greater value than it imported, a balance became due to it from foreign nations, which was necessarily paid to it in gold and silver, and thereby increased the quantity of those metals in the kingdom. But that when it imported to a greater value than it exported, a contrary balance became due to foreign nations, which was necessarily paid to them in the same manner, and thereby diminished that quantity: that in this case, to prohibit the exportation of those metals, could not prevent it, but only, by making it more dangerous, render it more expensive: that the exchange was thereby turned more against the country which owed the balance, than it otherwise might have been; the merchant who purchased a bill upon the foreign country being obliged to pay the banker who sold it, not only for the natural risk, trouble, and expense of sending the money thither, but for the extraordinary risk arising from the prohibition; but that the more the exchange was against any country, the more the balance of trade became necessarily against it; the money of that country becoming necessarily of so much less value, in comparison with that of the country to which the balance was due. That if the exchange between England and Holland, for example, was five per cent. against England, it would require 105 ounces of silver in England to purchase a bill for 100 ounces of silver in Holland: that 105 ounces of silver in England, therefore, would be worth only 100 ounces of silver in Holland, and would purchase only a proportionable quantity of Dutch goods; but that 100 ounces of silver in Holland, on the contrary, would be worth 105 ounces in England, and would purchase a proportionable quantity of English goods; that the English goods which were sold to Holland would be sold so much cheaper, and the Dutch goods which were sold to England so much dearer, by the difference of the exchange: that the one would draw so much less Dutch money to England, and the other so much more English money to Holland, as this difference amounted to: and that the balance of trade, therefore, would necessarily be so much more against England, and would require a greater balance of gold and silver to be exported to Holland.
Those arguments were partly solid and partly sophistical. They were solid, so far as they asserted that the exportation of gold and silver in trade might frequently be advantageous to the country. They were solid, too, in asserting that no prohibition could prevent their exportation, when private people found any advantage in exporting them. But they were sophistical, in supposing, that either to preserve or to augment the quantity of those metals required more the attention of government, than to preserve or to augment the quantity of any other useful commodities, which the freedom of trade, without any such attention, never fails to supply in the proper quantity. They were sophistical, too, perhaps, in asserting that the high price of exchange necessarily increased what they called the unfavourable balance of trade, or occasioned the exportation of a greater quantity of gold and silver. That high price, indeed, was extremely disadvantageous to the merchants who had any money to pay in foreign countries. They paid so much dearer for the bills which their bankers granted them upon those countries. But though the risk arising from the prohibition might occasion some extraordinary expense to the bankers, it would not necessarily carry any more money out of the country. This expense would generally be all laid out in the country, in smuggling the money out of it, and could seldom occasion the exportation of a single sixpence beyond the precise sum drawn for. The high price of exchange, too, would naturally dispose the merchants to endeavour to make their exports nearly balance their imports, in order that they might have this high exchange to pay upon as small a sum as possible. The high price of exchange, besides, must necessarily have operated as a tax, in raising the price of foreign goods, and thereby diminishing their consumption. It would tend, therefore, not to increase, but to diminish, what they called the unfavourable balance of trade, and consequently the exportation of gold and silver.
Such as they were, however, those arguments convinced the people to whom they were addressed. They were addressed by merchants to parliaments and to the councils of princes, to nobles, and to country gentlemen; by those who were supposed to understand trade, to those who were conscious to them selves that they knew nothing about the matter. That foreign trade enriched the country, experience demonstrated to the nobles and country gentlemen, as well as to the merchants; but how, or in what manner, none of them well knew. The merchants knew perfectly in what manner it enriched themselves, it was their business to know it. But to know in what manner it enriched the country, was no part of their business. The subject never came into their consideration, but when they had occasion to apply to their country for some change in the laws relating to foreign trade. It then became necessary to say something about the beneficial effects of foreign trade, and the manner in which those effects were obstructed by the laws as they then stood. To the judges who were to decide the business, it appeared a most satisfactory account of the matter, when they were told that foreign trade brought money into the country, but that the laws in question hindered it from bringing so much as it otherwise would do. Those arguments, therefore, produced the wished-for effect. The prohibition of exporting gold and silver was, in France and England, confined to the coin of those respective countries. The exportation of foreign coin and of bullion was made free. In Holland, and in some other places, this liberty was extended even to the coin of the country. The attention of government was turned away from guarding against the exportation of gold and silver, to watch over the balance of trade, as the only cause which could occasion any augmentation or diminution of those metals. From one fruitless care, it was turned away to another care much more intricate, much more embarrassing, and just equally fruitless. The title of Mun’s book, England’s Treasure in Foreign Trade, became a fundamental maxim in the political economy, not of England only, but of all other commercial countries. The inland or home trade, the most important of all, the trade in which an equal capital affords the greatest revenue, and creates the greatest employment to the people of the country, was considered as subsidiary only to foreign trade. It neither brought money into the country, it was said, nor carried any out of it. The country, therefore, could never become either richer or poorer by means of it, except so far as its prosperity or decay might indirectly influence the state of foreign trade.
A country that has no mines of its own, must undoubtedly draw its gold and silver from foreign countries, in the same manner as one that has no vineyards of its own must draw its wines. It does not seem necessary, however, that the attention of government should be more turned towards the one than towards the other object. A country that has wherewithal to buy wine, will always get the wine which it has occasion for; and a country that has wherewithal to buy gold and silver, will never be in want of those metals. They are to be bought for a certain price, like all other commodities; and as they are the price of all other commodities, so all other commodities are the price of those metals. We trust, with perfect security, that the freedom of trade, without any attention of government, will always supply us with the wine which we have occasion for; and we may trust, with equal security, that it will always supply us with all the gold and silver which we can afford to purchase or to employ, either in circulating our commodities or in other uses.
The quantity of every commodity which human industry can either purchase or produce, naturally regulates itself in every country according to the effectual demand, or according to the demand of those who are willing to pay the whole rent, labour, and profits, which must be paid in order to prepare and bring it to market. But no commodities regulate themselves more easily or more exactly, according to this effectual demand, than gold and silver; because, on account of the small bulk and great value of those metals, no commodities can be more easily transported from one place to another; from the places where they are cheap, to those where they are dear; from the places where they exceed, to those where they fall short of this effectual demand. If there were in England, for example, an effectual demand for an additional quantity of gold, a packet-boat could bring from Lisbon, or from wherever else it was to be had, fifty tons of gold, which could be coined into more than five millions of guineas. But if there were an effectual demand for grain to the same value, to import it would require, at five guineas a-ton, a million of tons of shipping, or a thousand ships of a thousand tons each. The navy of England would not be sufficient.
