To minimize conflicts in the future we should aim to create a world in which people are free to buy what they want, live and work where they choose, and invest and produce where conditions seem most propitious. There should be unlimited freedom for individuals to trade within and across national borders, widespread international division of labor, and worldwide economic interdependence. Would-be traders should encounter no restrictions or barriers to trade, enacted out of a misguided belief in economic nationalism and the supposed advantages of economic self-sufficiency. Friendships among individuals living in different parts of the world would then be reinforced daily through the benefits they reap from buying and selling with one another. Thus a sound basis for peaceful international relations would be encouraged.
