Dennis Gee, britisk skoleinspektør og ansat i en fagforening for lærere, om, hvorfor uddannelses-vouchers er en dårlig idé: “I’m not sure that parents know what is best educationally for their children. They know what’s best for them to eat. They know the best environment they can provide at home. But we’ve been trained to ascertain the problems of children, to detect their weaknesses, to put right those things that need putting right, and we want to do this freely, with the cooperation of parents and not under undue strains.” (Citeret i Milton & Rose Friedman, Free to Choose, 1980)
