The following paragraphs are taken from Ayn Rand’s classic “Capitalism: the unknown ideal”.
Wars are the second greatest evil that human societies can perpetrate. The first is dictatorship, the enslavement of their own citizens, which is the cause of wars.
Laissez-faire capitalism is the only social system based on the recognition of individual rights and, therefore, the only system that bans force from social relationships. By the nature of its basic principles and interests, it is the only system fundamentally opposed to war.
Men who are free to produce, have no incentive to loot; they have nothing to gain from war and a great deal to lose. Ideologically, the principle of individual rights does not permit a man to seek his own livelihood at the point of a gun, inside or outside his country. Economically, wars cost money; in a free economy, where wealth is privately owned, the costs of war come out of the income of private citizens—there is no overblown public treasury to hide that fact—and a citizen cannot hope to recoup his own financial losses (such as taxes or business dislocations or property destruction) by winning the war. Thus his own economic interests are on the side of peace.
In a statist economy, where wealth is “publicly owned,” a citizen has no economic interests to protect by preserving peace—he is only a drop in the common bucket—while war gives him the (fallacious) hope of larger handouts from his master. Ideologically, he is trained to regard men as sacrificial animals; he is one himself; he can have no concept of why foreigners should not be sacrificed on the same public altar for the benefit of the same state.
The trader and the warrior have been fundamental antagonists throughout history. Trade does not flourish on battlefields, factories do not produce under bombardments, profits do not grow on rubble. Capitalism is a society of traders—for which it has been denounced by every would-be gunman who regards trade as “selfish” and conquest as “noble.”
Let those who are actually concerned with peace observe that capitalism gave mankind the longest period of peace in history—a period during which there were no wars involving the entire civilized world—from the end of the Napoleonic wars in 1815 to the outbreak of World War I in 1914.
Statism—in fact and in principle—is nothing more than gang rule. A dictatorship is a gang devoted to looting the effort of the productive citizens of its own country. When a statist ruler exhausts his own country’s economy, he attacks his neighbors. It is his only means of postponing internal collapse and prolonging his rule. A country that violates the rights of its own citizens, will not respect the rights of its neighbors. Those who do not recognize individual rights, will not recognize the rights of nations: a nation is only a number of individuals.
Statism needs war; a free country does not. Statism survives by looting; a free country survives by production.
Observe that the major wars of history were started by the more controlled economies of the time against the freer ones. For instance, World War I was started by monarchist Germany and Czarist Russia, who dragged in their freer allies. World War II was started by the alliance of Nazi Germany with Soviet Russia and their joint attack on Poland.
Observe that in World War II, both Germany and Russia seized and dismantled entire factories in conquered countries, to ship them home—while the freest of the mixed economies, the semi-capitalistic United States, sent billions worth of lend-lease equipment, including entire factories, to its allies.
Germany and Russia needed war; the United States did not and gained nothing. (In fact, the United States lost, economically, even though it won the war: it was left with an enormous national debt, augmented by the grotesquely futile policy of supporting former allies and enemies to this day.) Yet it is capitalism that today’s peace-lovers oppose and statism that they advocate—in the name of peace.
If men want to oppose war, it is statism that they must oppose. So long as they hold the tribal notion that the individual is sacrificial fodder for the collective, that some men have the right to rule others by force, and that some (any) alleged “good” can justify it—there can be no peace within a nation and no peace among nations.
Just as, in domestic affairs, all the evils caused by statism and government controls were blamed on capitalism and the free market—so, in foreign affairs, all the evils of statist policies were blamed on and ascribed to capitalism. Such myths as “capitalistic imperialism,” “war-profiteering,” or the notion that capitalism has to win “markets” by military conquest are examples of the superficiality or the unscrupulousness of statist commentators and historians.
The essence of capitalism’s foreign policy is free trade—i.e., the abolition of trade barriers, of protective tariffs, of special privileges—the opening of the world’s trade routes to free international exchange and competition among the private citizens of all countries dealing directly with one another. During the nineteenth century, it was free trade that liberated the world, undercutting and wrecking the remnants of feudalism and the statist tyranny of absolute monarchies.
Remember that private citizens—whether rich or poor, whether businessmen or workers—have no power to start a war. That power is the exclusive prerogative of a government. Which type of government is more likely to plunge a country into war: a government of limited powers, bound by constitutional restrictions—or an unlimited government, open to the pressure of any group with warlike interests or ideologies, a government able to command armies to march at the whim of a single chief executive?
