"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 FriedmanIf freedom led to wider inequality, I would prefer that to a world in which I got artificial equality at the expense of freedom. My objective, my god... is freedom of individuals to pursue their own values.
Milton FriedmanThere is not a line in 'The Wealth of Nations' that is not still applicable to this day.
Milton FriedmanThe countries that have risen and separated out as a result of the collapse of the Soviet Union are, on the whole, following freer economic policies. Most of these states have freer government and less restrictions on trade.
Milton FriedmanThe great virtue of a free market system is that it does not care what color people are; it does not care what their religion is; it only cares whether they can produce something you want to buy. It is the most effective system we have discovered to enable people who hate one another to deal with one another and help one another.
