This is part three of eight in a series on the morality of capitalism. Free markets are probably the greatest force for peace in history. There are three distinct ways in which capitalism promotes peace. A negative system The simplest way in which capitalism is peaceful is by its abstention from direct acts of violence. Free markets offer no positive prescription for what market participants must do. A genuine capitalist system is one of free trade and voluntary association. People are free to do, in the words of Leonard Read, “Anything that’s peaceful.” There are no “do’s,” and the only real “don’t” at bottom is, “don’t use force.” All else is permitted, but there is no guarantee the market will sustain or reward it. Capitalism is not a master plan or a system created ahead of time by planners. It is really just the result of peaceful interactions. It is what emerges if force is only used in defense against force. The absence of violence results in secure property rights, contracts and all of the other institutional trappings that are commonly associated with capitalism. Every other economic system requires a direct application of violence. Any regulation, fee, tax, trade barrier, licensing regime or mandate offered in any kind of “mixed” or corporatist or socialist or fascist regime is backed by the threat of violence. Raising the cost of violence Beyond the absence of force in individual actions, capitalism promotes a much broader peace between people groups from different regions and of different cultures and backgrounds. Self-interest begets trade; trade begets specialization; specialization begets cooperation. Ricardo’s law of association demonstrates how much more productive we are when we specialize and trade, which means that over time we come to rely on a vast network of trading partners for our own well-being. Some people find this state of affairs troubling and you hear things like, “What if X country decides to withhold good Y from us? We rely too heavily on imports!” There are plenty of natural and man-made things to fear in the world if you wish to worry, but the cutting off of trade in a truly free market ought not to be one of them. If a person genuinely wants to avoid all reliance on other people (not sure how this would work for a newborn), they are free to live as long as they can only eat what they can find or grow on their own. It’s not hard to see that that kind of “independence” is far more risky than being part of an interdependent trade network. The more people rely on trade with others, the greater the cost to all parties of a conflict. If I grow apples and trade them to you for chickens, the last thing I want to do is tick you off and lose my chicken supply and vice versa. On the flip side, if you have a lot of chickens and I have none, and there is no trade between us, I will be tempted to try stealing some. Lack of trade builds enmity. There is a famous saying, attributed to Frederic Bastiat, “If goods don’t cross borders, armies will.” In a free market, the cost of belligerence is very high. When governments come in and restrict trade or subsidize violence by building up large militaries, the cost of belligerence is lowered, and the benefits of peace are reduced. It is the state, not trade, which creates conflict. Friends, not enemies Pretend you live in a free-market economy. You are friends with your neighbor, who works at a small grocer in town. You find the selection to be limited and the prices high. A new supermarket chain is coming in to town, and you’re excited about it because the lower prices and better selection mean you’ll have better meals and money left over for leisure activities with your family. Your neighbor is unhappy about the new store because it may cost him his job. The store comes in. You shop there and save while also expressing your heartfelt empathy to your neighbor whose store may soon shut down. You maintain your friendship, even though in the economic sphere you cease to be trading partners. Now pretend you live in a heavily regulated economic system much like ours today. You and your neighbor the grocer are still friends. This time the chain store is not free to sell in your town without a government permission slip. It goes up for a vote. Your neighbor actively campaigns to restrain the store from opening up, which will prevent you from buying better products for less money. He urges you to join his efforts and put a “No chain stores!” sign in your yard. You tell him that you won’t because you wouldn’t mind the chain store. It turns in to a bitter, possibly friendship-ending disagreement. Politics makes enemies out of friends. In a market, you are free to express your varied preferences with your own actions and the expenditure of your own resources. If someone sells something you don’t like, you don’t have to buy. But the very anonymity and absence of compulsion in markets allows you to form community bonds quite separate from your trading choices. You can maintain friendships with all kinds of people whose goods and services you do not necessarily value. You can befriend an orchestral violinist without being a patron of the symphony. But when resources are allocated politically rather than in a free market, that friendship is hard to maintain when you would vote against a tax to fund the symphony hall, which she supports. Capitalism allows our diverse tastes to be explored and expressed in a way that doesn’t restrict choices to zero-sum contests of your preferences over others. A cornucopia of choice exists in the market, and this not only means better products, but also the removal of artificially created conflict between choices A and B, such as those that inevitably spring from government management. Three kinds of peace Capitalism relies on voluntarism rather than violence in individual interactions. It also creates cooperative networks that dramatically increase the incentive to get along and raise the cost of conflict, while government intervention does just the opposite. Finally, capitalism allows us to live in harmony despite our different tastes and sometimes conflicting demands for limited resources, while political allocation always forces us to take sides and go to battle against each other. If you want a more peaceful world, promote capitalism.
