Silence was pleased. - Milton Friedman

The price that the market sets on the services of our resources is similarly affected by a bewildering mixture of chance and choice. Frank Sinatra’s voice was highly valued in twentieth-century United States. Would it have been highly valued in twentieth-century India, if he had happened to be born and to live there? Skill as a hunter and trapper had a high value in eighteenth- and nineteenth-century America, a much lower value in twentieth-century America. Skill as a baseball player brought much higher returns than skill as a basketball player in the 1920s; the reverse is true in the 1970s. These are all matters involving chance and choice — in these examples, mostly the choices made by consumers of services that determine the relative market prices of different items.

History only suggests that capitalism is a necessary condition for political freedom. Clearly it is not a sufficient condition.

A stable and democratic society is impossible without a minimum degree of literacy and knowledge on the part of most citizens and without widespread acceptance of some common set of values. Education can contribute to both. In consequence, the gain from the education of a child accrues not only to the child or to his parents but also to other members of the society.
