Friedman's "Tyranny of the Status Quo"

One of the living legend of liberal economists is Prof Sowell. Some excerpts from his article on Friedman:

• "No one converted Milton Friedman, either in economics or in his views on social policy. His own research, analysis and experience converted him.
• As a professor, he did not attempt to convert students to his political views. I made no secret of the fact that I was a Marxist when I was a student in Professor Friedman's course, but he made no effort to change my views. He once said that anybody who was easily converted was not worth converting.
• I was still a Marxist after taking Professor Friedman's class. Working as an economist in the government converted me."
