"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 FriedmanBecause it is one thing to have free immigration to jobs. It is another thing to have free immigration to welfare. And you cannot have both. If you have a welfare state, if you have a state in which every resident is promises a certain minimal level of income, or a minimum level of subsistence, regardless of whether he works or not, produces it or not. Then it really is an impossible thing.
Milton FriedmanEconomics has become increasingly an arcane branch of mathematics rather than dealing with real economic problems.

Milton FriedmanThe free man will ask neither what his country can do for him nor what he can do for his country. He will ask rather 'What can I and my compatriots do through government' to help us discharge our individual responsibilities, to achieve our several goals and purposes, and above all, to protect our freedom?
Milton FriedmanIf instead of looking at income, you look at levels of consumption, if anything that's become more equal. The fraction of families that have a dishwasher, that have a sewing machine, that have a television set. In respect to consumption, it's very hard to avoid the view that people have been getting more equal rather than more unequal.
