Rediscovering Friedman's Capitalism and Freedom

I first read the following paragraph as a nerdy college student sometime between 1966 and 1968:  

In a much quoted passage in his inaugural address, President Kennedy said, ‘Ask not what your country can do for you – ask what you can do for your country.' It is a striking sign of the temper of our times that the controversy about this passage centered on its origin and not on its content. Neither half of the statement expresses a relation between citizen and his government that is worthy of the ideals of free men in a free society.”
