In a free economy, where no man or group of men can use physical coercion against anyone, economic power can be achieved only by voluntary means: by the voluntary choice and agreement of all those who participate in the process of production and trade. In a free market, all prices, wages, and profits are determined—not by the arbitrary whim of the rich or of the poor, not by anyone’s “greed” or by... anyone’s need—but by the law of supply and demand. The mechanism of a free market reflects and sums up all the economic choices and decisions made by all the participants.

 

Men trade their goods or services by mutual consent to mutual advantage, according to their own independent, uncoerced judgment. A man can grow rich only if he is able to offer better values—better products or services, at a lower price—than others are able to offer.
Wealth, in a free market, is achieved by a free, general, “democratic” vote—by the sales and the purchases of every individual who takes part in the economic life of the country. Whenever you buy one product rather than another, you are voting for the success of some manufacturer. And, in this type of voting, every man votes only on those matters which he is qualified to judge: on his own preferences, interests, and needs. No one has the power to decide for others or to substitute his judgment for theirs; no one has the power to appoint himself “the voice of the public” and to leave the public voiceless and disfranchised. - Ayn Rand -
