...theories should be judged by their ability to predict events rather than by the realism of their assumptions.
Milton FriedmanGermany has a very able and productive workforce. It has high-quality products that are valued all over the world. It has every opportunity to be a productive, growing state. It just has to give its entrepreneurs a chance. It has to let them make money, hire and fire, and act like entrepreneurs.
Milton FriedmanThe preservation of liberty, not the promotion of efficiency, is the primary justification for private property. Efficiency is a happy, though not accidental, by-product - and a most important by-product because liberty could not have survived if it had not also produced affluence.
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 FriedmanNobody spends somebody else's money as carefully as he spends his own. Nobody uses somebody else's resources as carefully as he uses his own. So if you want efficiency and effectiveness, if you want knowledge to be properly utilized, you have to do it through the means of private property.
