Because 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 FriedmanThe great virtue of a free market is that it enables people who hate each other, or who are from vastly different religious or ethnic backgrounds, to cooperate economically. Government intervention can't do that.
Milton FriedmanOne of the great mistakes is to judge policies and programs by their intentions rather than their results.
Milton FriedmanIf you spend your own money on yourself, you care how much you spend and how well you spend it. If you spend your own money on someone else, you care how much you spend, but you don't care how well it is spent. If you spend someone else's money on yourself, you don't care how much you spend, but you do care how well it is spent. And finally, if you spend someone else's money on someone else, you don't care how much you spend, and you don't care how well it is spent. That is government.
Milton FriedmanThe Fed was largely responsible for converting what might have been a garden-variety recession, although perhaps a fairly severe one, into a major catastrophe. Instead of using its powers to offset the depression, it presided over a decline in the quantity of money by one-third from 1929 to 1933 ... Far from the depression being a failure of the free-enterprise system, it was a tragic failure of government.
