It [the free market] is an organizational way of doing things, featuring openness, which enables millions of people to cooperate and compete without demanding a preliminary clearance of pedigree, nationality, color, race, religion, or wealth. It demands only that each person abide by voluntary principles, that is, by fair play. The free market means willing exchange; it is impersonal justice in the economic sphere and excludes coercion, plunder, theft, protectionism, and other anti-free market ways by which goods and services change hands.
