This program is introduced by David Friedman, Milton's son. He argues that education is too important to allow the government a role, saying, "After all, if the government is in charge of delivering the mail, all that means is that some of our letters get lost. If governments are in charge of running the schools, that means that some of our children never learn to read." In the filmed documentary, Milton Friedman uses U.S. public education as a case study of the failure of socialism. Socialism, he says, is based on the premise that people are better off if experts guide their lives. Government bureaucrats have replaced parents as decision-makers in American public education. Friedman endorses a voucher system to give choice and control back to parents. "Parental choice, parents choosing the teachers, parents monitoring the schooling," is Friedman's answer to the problem. In almost every case, giving individuals the power to choose, to set their own course, will lead to better results than centrally planned activity. After the documentary, Friedman explores the subject further with Gordon Tullock of the University of Arizona and Henry Levin of Stanford University. They debate what standards government should set for education, the role of public and private schools, the special needs of underprivileged children, and how much control parents should have over the schools.
