Many people oppose the free market because it leads to inequality of wealth and income. It is unfair, they say, that some people have vastly more money than others. Some defenders of the free market respond that these inequalities, while undesirable in themselves, make the poor better off than they would be otherwise, and so should be accepted. Another argument made by defenders of the free market is that restricting inequality would interfere liberty, so that, although inequality is bad, we have to put up with it.
While it is true that inequality makes the poor better off and that restricting inequality interferes with liberty, these are not the best arguments that defenders of the free market should use. They accept that inequality is bad, but we should reject this assumption. There is nothing bad about inequality.
People are unequal in every dimension of their being, including weight, height, muscle build, intelligence, and so on. This just the way the world is. Why should we try to change it? People who attempt this have a grudge against the world. They are not satisfied with the way God created it.
And of course they can’t succeed. As the great Murray Rothbard points out, absolute equality is impossible. No two places on earth, for example, offer precisely the same view.
If we shouldn’t defend the free market by arguing that it decreases equality, what should we do? Fortunately, there are many better arguments available. I’m going to list a number of them, but if you want more details, you should read Murray Rothbard’s Power and Market and Ludwig von Mises’s Human Action.
One of the best of these arguments is that the free market makes possible mutually beneficial gains from trade. If I have something that you want and you have something I want, we can make an exchange, so we are both better off. But what if our exchange makes someone else worse off? This question is a version of the “externalities” or “market failure” argument. The claim is that some of our activities, including trade, impose costs on others. If so, this indicates a failure to define property rights. Once we do so, the so-called “problem” dissolves.
