Spending by government currently amounts to about 45 percent of national income. By that test, government owns 45 percent of the means of production … - Milton Friedman

By relying primarily on voluntary co-operation and private enterprise, in both economic and other activities, we can insure that the private sector is a check on the powers of the governmental sector and an effective protection of freedom of speech, of religion, and of thought.

Fundamentally, there are only two ways of coordinating the economic activities of millions. One is central direction involving the use of coercion—the technique of the army and of the modern totalitarian state. The other is voluntary co-operation of individuals—the technique of the market place.

Because we live in a largely free society, we tend to forget how limited is the span of time and the part of the globe for which there has ever been anything like : the typical state of mankind is tyranny, servitude, and misery. The nineteenth century and early twentieth century in the Western world stand out as striking exceptions to the general trend of historical development. Political freedom in this instance clearly came along with the free market and the development of capitalist institutions. So also did political freedom in the golden age of Greece and in the early days of the Roman era. History suggests only that capitalism is a necessary condition for political freedom. Clearly it is not a sufficient condition.
