"The compulsory attendance laws are the justification for government control over the standards of private schools. But it is far from clear that there is any justification for the compulsory attendance laws themselves. Our own views on this have changed over time. When we first wrote extensively a quarter of a century ago on this subject, we accepted the need for such laws on the ground that "a stable democratic society is impossible without a minimum degree of literacy and knowledge on the part of most citizens."15 We continue to believe that, but research that has been done in the interim on the history of schooling in the United States, the United Kingdom, and other countries has persuaded us that compulsory attendance at schools is not necessary to achieve that minimum standard of literacy and knowledge. As already noted, such research has shown that schooling was well-nigh universal in the United States before attendance was required. In the United Kingdom, schooling was well-nigh universal before either compulsory attendance or government financing of schooling existed. Like most laws, compulsory attendance laws have costs as well as benefits. We no longer believe the benefits justify the costs. We realize that these views on financing and attendance laws will appear to most readers to be extreme. That is why we only state them here to keep the record straight without seeking to support them at length. Instead, we return to the voucher plan — - a much more moderate departure from present practice."

The combination of economic and political power in the same hands is a sure recipe for tyranny.

Labor unions can and often do provide useful services for their members — negotiating the terms of their employment, representing them with respect to grievances, giving them a feeling of belonging and participating in a group activity, among others. As believers in freedom, we favor the fullest opportunity for voluntary organization of labor unions to perform whatever services their members wish, and are willing to pay for, provided they respect the rights of others and refrain from using force. However, unions and comparable groups such as the professional associations have not relied on strictly voluntary activities and membership with respect to their major proclaimed objective — improving the wages of their members. They have succeeded in getting government to grant them special privileges and immunities, which have enabled them to benefit some of their members and officials at the expense of other workers and all consumers. In the main, the persons benefited have had decidedly higher incomes than the persons harmed.
