CHAPTER X. OF INTERFERENCES OF GOVERNMENT GROUNDED ON § 1. FROM the necessary functions of government, and the effects produced on the economical interests of society by their good or ill discharge, we proceed to the functions which belong to what I have termed, for want of a better designation, the optional class; those which are sometimes assumed by governments and sometimes not, and which it is not unanimously admitted that they ought to exercise. Before entering on the general principles of the question, it will be advisable to clear from our path all those cases, in which government interference works ill, because grounded on false views of the subject interfered with. Such cases have no connexion with any theory respecting the proper limits of interference. There are some things with which governments ought not to meddle, and other things with which they ought; but whether right or wrong in itself, the interference must work for ill, if government, not understanding the subject which it meddles with, meddles to bring about a result which would be mischievous. We will therefore begin by passing in review various false theories, which have from time to time formed the ground of acts of government more or less economically injurious. Former writers on political economy have found it needful to devote much trouble and space to this department of their subject. It has now happily become possible, at least in our own country, greatly to abridge this purely negative part of our discussions. The false theories of political economy which have done so much mischief in times past, are entirely discredited among all who have not lagged behind the general progress of opinion; and few of the enactments which were once grounded on those theories still help to deform the statute-book. As the principles, on which their condemnation rests, have been fully set forth in other parts of this treatise, we may here content ourselves with a few brief indications. Of these false theories, the most notable is the doctrine of Protection to Native Industry; a phrase meaning the prohibition, or the discouragement by heavy duties, of such foreign commodities as are capable of being produced at home. If the theory involved in this system had been correct, the practical conclusions grounded on it would not have been unreasonable. The theory was, that to buy things produced at home was a national benefit, and the introduction of foreign commodities, generally a national loss. It being at the same time evident that the interest of the consumer is to buy foreign commodities in preference to domestic whenever they are either cheaper or better, the interest of the consumer appeared in this respect to be contrary to the public interest; he was certain, if left to his own inclinations, to do what according to the theory was injurious to the public. It was shewn, however, in our analysis of the effects of international trade, as it had been often shewn by former writers, that the importation of foreign commodities, in the common course of traffic, never takes place, except when it is, economically speaking, a national good, by causing the same amount of commodities to be obtained at a smaller cost of labour and capital to the country. To prohibit, therefore, this importation, or impose duties which prevent it, is to render the labour and capital of the country less efficient in production than they would otherwise be; and compel a waste, of the difference between the labour and capital necessary for the home production of the commodity, and that which is required for producing the things with which it can be purchased from abroad. The amount of national loss thus occasioned is measured by the excess of the price at which the commodity is produced, over that at which it could be imported. In the case of manufactured goods, the whole difference between the two prices is absorbed in indemnifying the producers for waste of labour, or of the capital which supports that labour. Those who are supposed to be benefited, namely the makers of the protected articles, (unless they form an exclusive company, and have a monopoly against their own countrymen as well as against foreigners,) do not obtain higher profits than other people. All is sheer loss, to the country as well as to the consumer. When the protected article is a product of agriculture-the waste of labour not being incurred on the whole produce, but only on what may be called the last instalment of it-the extra price is only in part an indemnity for waste, the remainder being a tax paid to the landlords. The restrictive and prohibitory policy was originally grounded on what is called the Mercantile System, which representing the advantage of foreign trade to consist solely in bringing money into the country, gave artificial encouragement to exportation of goods, and discountenanced their importation. The only exceptions to the system were those required by the system itself. The materials and instruments of production were the subjects of a contrary policy, directed however to the same end; they were freely imported, and not permitted to be exported, in order that manufacturers, being more cheaply supplied with the requisites of manufacture, might be able to sell cheaper, and therefore to export more largely. For a similar reason, importation was allowed and even favoured, when confined to the productions of countries which were supposed to take from the country still more than it took from them, thus enriching it by a favourable balance of trade. As part of the same system, colonies were founded, for the supposed advantage of compelling them to buy our commodities, or at all events not to buy those of any other country in return for which restriction, we were generally willing to come under an equivalent obligation with respect to the staple productions of the colonists. The consequences of the theory were pushed so far, that it was not unusual even to give bounties on exportation, and induce foreigners to buy from us rather than from other countries, by a cheapness which we artificially produced, by paying part of the price for them, out of our own taxes. This is a stretch beyond the point yet reached by any private tradesman in his competition for business. No shopkeeper, I should think, ever made a practice of bribing customers by selling goods to them at a permanent loss, making it up to himself from other funds in his possession. The principle of the Mercantile Theory is now given up even by writers and governments who still cling to the restrictive system. Whatever hold that system has over men's minds, independently of the private interests exposed to real or apprehended loss by its abandonment, is derived from fallacies other than the old notion of the benefits of heaping up money in the country. The most effective of these is the specious plea of employing our own countrymen and our national industry, instead of feeding and supporting the industry of foreigners. The answer to this, from the principles laid down in former chapters, is evident. Without reverting to the fundamental theorem discussed in an early part of the present treatise,* respecting the nature and sources of employment for labour, it is sufficient to say, what has usually been said by the advocates of free trade, that the alternative is not between employing our own people and foreigners, but between employing one class and another of our own people. The imported commodity is always paid for, directly or indirectly, with the produce of our own industry: that industry being, at the same time, rendered more productive, since, with the same labour and outlay, we are enabled to possess ourselves of a greater quantity of the article. Those who have not * Supra, vol. i. pp. 98 et seqq. well considered the subject are apt to suppose that our exporting an equivalent in our own produce, for the foreign articles we consume, depends on contingencies-on the consent of foreign countries to make some corresponding relaxation of their own restrictions, or on the question whether those from whom we buy are induced by that circumstance to buy more from us; and that, if these things, or things equivalent to them, do not happen, the payment must be made in money. Now, in the first place, there is nothing more objectionable in a money payment than in payment by any other medium, if the state of the market makes it the most advantageous remittance; and the money itself was first acquired, and would again be replenished, by the export of an equivalent value of our own products. But, in the next place, a very short interval of paying in money would so lower prices as either to stop a part of the importation, or raise up a foreign demand for our produce, sufficient to pay for the imports. I grant that this disturbance of the equation of international demand would be in some degree to our disadvantage, in the purchase of other imported articles; and that a country which prohibits some foreign commodities, does, cæteris paribus, obtain those which it does not prohibit, at a less price than it would otherwise have to pay. To express the same thing in other words; a country which destroys or prevents altogether certain branches. of foreign trade, thereby annihilating a general gain to the world, which would be shared in some proportion between itself and other countries- does, in some circumstances, draw to itself, at the expense of foreigners, a larger share than would else belong to it of the gain arising from that portion of its foreign trade which it suffers to subsist. But even this it can only be enabled to do, if foreigners do not maintain equivalent prohibitions or restrictions against its commodities. In any case, the justice or expediency of destroying one of two gains, in order to engross a rather larger share of the other, does not require much discussion: the |
