To the best of my knowledge, there has never been a monetary union, putting out a fiat currency, composed of independent states.
Milton FriedmanThe black market was a way of getting around government controls. It was a way of enabling the free market to work. It was a way of opening up, enabling people.
Milton FriedmanUnderlying most arguments against the free market is a lack of belief in freedom itself.
Milton FriedmanA private enterprise system needs some measuring rod, it needs something, it needs money to make its transactions. You can't run a big complicated system through barter, through converting one commodity into another. You need a monetary system to operate. And the instability in that monetary system is devastating to the performance of the economy.
Milton FriedmanThe only reason there is a crisis about Social Security in the US and pensions in Europe and Japan is that you cannot maintain a "Ponzi" scheme indefinitely. We have collected from today's young to pay today's old and counted on tomorrow's young to keep doing so. That was a fine scheme as long as the number of young people was rising faster than old people. When that ratio comes to an end, such a system also has to end.
