Milton Friedman. His argument is a simple one: the best way to improve our children’s schools is to introduce competition. If schools compete, kids win. And if schools compete, those who are the least advantaged have the most to gain. Wealthy families already have “school choice,” because they can send their children to private schools. If we give parents vouchers to send their children to any school they want, then we will put children from poor families more nearly on a par with their more privileged middle- and upper-class counterparts.
