The Great Depression was not a sign of the failure of monetary policy or a result of the failure of the market system as was widely interpreted. It was instead a consequence of a very serious government failure, in particular a failure in the monetary authorities to do what they'd initially been set up to do.
Milton FriedmanDoing good with other people's money has two basic flaws. In the first place, you never spend anybody else's money as carefully as you spend your own. So a large fraction of that money is inevitably wasted. In the second place, and equally important, you cannot do good with other people's money unless you first get the money away from them. So that force - sending a policeman to take the money from somebody's pocket - is fundamentally at the basis of the philosophy of the welfare state.
Milton FriedmanThe collapse of communism in essence added tens and tens of millions of people to the world labor supply, and the people who were added had previously been getting very low income, but they were not unskilled. Many of them were fairly well educated.
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.
