The state has not the right to monopolize education. Education is a legitimate form of private enterprise, subject indeed to a certain amount of government regulation, but there is notrhing in its nature that makes it a public or private monopoly. The reason is that the primary right to educate their children belongs to the parents. In understanding the work of education, the state is simply supplying the parents with facilities to fulfill their duty. If the parents have other facilities at their command, they have no obligation to use those the state provides. (p. 437)
