Government means always coercion and compulsion and is by necessity the opposite of liberty. Government is a guarantor of liberty and is compatible with liberty only if its range is adequately restricted to the preservation of economic freedom. Where there is no market economy, the best-intentioned provisions of constitutions and laws remain a dead letter.

“The freedom of man under capitalism is an effect of competition.”

The worker does not depend on the good graces of an employer. If his employer discharges him, he finds another employer. 14 The consumer is not at the mercy of the shopkeeper. He is free to patronize another shop if he likes. Nobody must kiss other people's hands or fear their disfavor. Interpersonal relations are businesslike. The exchange of goods and services is mutual; it is not a favor to sell or to buy, it is a transaction dictated by selfishness on either side.
