A disastrous intellectual package-deal, put over on us by the theoreticians of statism, is the equation of economic power with political power. You have heard it expressed in such bromides as: “A hungry man is not free,” or “It makes no difference to a worker whether he takes orders from a businessman or from a bureaucrat.” Most people accept these equivocations—and yet they know that the poorest laborer in America is freer and more secure than the richest commissar in Soviet Russia. What is the basic, the essential, the crucial principle that differentiates freedom from slavery? It is the principle of voluntary action versus physical coercion or compulsion.

No individual or private group or private organization has the legal power to initiate the use of physical force against other individuals or groups and to compel them to act against their own voluntary choice. Only a government holds that power. The nature of governmental action is: coercive action. The nature of political power is: the power to force obedience under threat of physical injury—the threat of property expropriation, imprisonment, or death.

Foggy metaphors, sloppy images, unfocused poetry, and equivocations—such as “A hungry man is not free”—do not alter the fact that only political power is the power of physical coercion and that freedom, in a political context, has only one meaning: the absence of physical coercion.
