The second flaw is the assumption of a limited amount of market, which carries with it the assumption that the groups of traders, gathered under their national flags, are engaged in a conflict in which they are entitled to embroil their governments. By tariff bargaining and by all sorts of diplomatic weapons each government is called upon to assist its nationals and to cripple or exclude the nationals of other states. Now it is untrue that the world market is strictly limited, with the consequence that every advance of one group of traders is at the expense of another group. The world market is indefinitely expansible, and is always expanding; and commercial experience shows that the rapid expansion of the overseas trade of one country does not preclude the expansion of trade of other countries. I do not, of course, deny that at a particular time and in relation to some particular lucrative opportunity, genuine clashes of interests may arise. But, envisaging the whole range of foreign commerce, one feels that the image of it as a prize which governments can, and ought to win for their traders at the expense of the traders supported by other governments, has been a most fertile source of international misunderstanding. Perhaps the worst of the three fallacies, and in a sense the deepest-rooted, is the concept of export trade as of more value than import trade. This is often traced back to the time when governments deemed it desirable to accumulate in their countries treasures of gold and silver and to this end encouraged the sale of goods abroad and discouraged the payment for them in foreign goods. There are, however, modern supporters of the assumption that it is more important to sell than to buy, although the money received for sales has no other significance or value than its power to buy, and trade can only be imaged truly as an exchange of goods for goods in which the processes of selling and of buying are complementary. The economic explanation of the double falsehood of dividing buying from selling and of imputing a higher value to the latter process, lies beyond the scope of this address. But the injuries resulting from the superior pressure upon governments of organized bodies of producers and merchants who have things to sell, to the detriment of the consuming public who have only buying needs, are too grave matters to be neglected here. It is not too much to say that, if the interests of consumers and the interests of producers weighed equally in the eyes of governments, as they should, the strongest of all obstacles to a peaceful, harmonious society of nations would be overcome. For the suspicions, jealousies, and hostilities of nations are inspired more by the tendency of groups of producers to misrepresent their private interests as the good of their respective countries than by any other single circumstance.
