"We have a simple problem in this country" when it comes to education, says Robert C. Enlow, president of the Friedman Foundation for Educational Choice. "And that's a monopoly. It's not the people in the system. It's the system itself." Nobel Prize-winning economist Milton Friedman (1912-2006) introduced the concept of school vouchers in a 1955 essay and, with his wife Rose (1910-2009), created the foundation that bears their name in 1996.
