"Free markets" is a very general term. There are all sorts of problems that will emerge. Free markets work best when the transaction between two individuals affects only those individuals. Most often, a transaction between you and me affects a third party. That is the source of all problems for government. That is the source of all pollution problems, of the inequality problem. This reality ensures that the end of history will never come.
Milton FriedmanYou had a flood of immigrants, millions of them, coming to this country. What brought them here? It was the hope for a better life for them and their children. And, in the main, they succeeded. It is hard to find any century in history, in which so large a number of people experience so great an improvement in the conditions of their life, in the opportunities open to them, as in the period of the 19th and early 20th century.
Milton FriedmanI am a libertarian with a small "l" and a Republican with a capital "R". And I am a Republican with a capital "R" on grounds of expediency, not on principle.
