The most important single central fact about a free market is that no exchange takes place unless both parties benefit.
Interpretation
A free market thrives on mutual benefit, ensuring that all parties gain from their exchanges.
Milton Friedman emphasizes the fundamental principle of a free market economy: transactions occur voluntarily and are beneficial for both participating parties. This mutual benefit drives trade and economic growth, reflecting the inherent value of cooperation and the pursuit of self-interest within a market system.
In practice
This quote can be used in an economic lecture to explain the principles of market exchanges.
The economic miracle that has been the United States was not produced by socialized enterprises, by government-unon-industry cartels or by centralized economic planning. It was produced by private enterprises in a profit-and-loss system. And losses were at least as important in weeding out failures, as profits in fostering successes. Let government succor failures, and we shall be headed for stagnation and decline.
Universities exist to transmit knowledge and understanding of ideas and values to students not to provide entertainment for spectators or employment for athletes.
There is no place for government to prohibit consumers from buying products the effect of which will be to harm themselves.
There is one and only one social responsibility of business - to use it resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say, engages in open and free competition without deception or fraud.
The great danger to the consumer is the monopoly -whether private or governmental. His most effective protection is free competition at home and free trade throughout the world. The consumer is protected from being exploited by one seller by the existence of another seller from whom he can buy and who is eager to sell to him. Alternative sources of supply protect the consumer far more effectively than all the Ralph Naders of the world.
The strongest argument for free enterprise is that it prevents anybody from having too much power. Whether that person is a government official, a trade union official, or a business executive. If forces them to put up or shut up. They either have to deliver the goods, produce something that people are willing to pay for, are willing to buy, or else they have to go into a different business.
A banker who is allowed to borrow money at X and loan it out at X plus Y will just go crazy and do too much of it if the civilization doesn't have rules that prevent it.
One of the most powerful insights in economics is this idea of a division of labor. You do the thing you're good at. Other people do something else that they're good at. The net effect is better for everybody.
What someone is paid has little or no relationship to what their work is worth to society.
The public firm can nowhere maintain itself in free competition with the private firm; it is possible today only where it has a monopoly that excludes competition. Even that alone is evidence of its lesser economic productivity.
Once you realize that trickle-down economics does not work, you will see the excessive tax cuts for the rick as what they are -- a simple upward redistribution of income, rather than a way to make all of us richer, as we were told.
If low taxes were the way that people like me created wealth, then we'd be starting our companies in the Congo or Somalia or Afghanistan, but we're not. We come to places where there are lots and lots of customers.
