Nobody 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.
Milton FriedmanKeynes was a great economist. In every discipline, progress comes from people who make hypotheses, most of which turn out to be wrong, but all of which ultimately point to the right answer. Now Keynes, in 'The General Theory of Employment, Interest and Money,' set forth a hypothesis which was a beautiful one, and it really altered the shape of economics. But it turned out that it was a wrong hypothesis. That doesn't mean that he wasn't a great man!
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 FriedmanThe great virtue of free enterprise is that it forces existing businesses to meet the test of the market continuously, to produce products that meet consumer demands at lowest cost, or else be driven from the market. It is a profit-and-loss system. Naturally, existing businesses generally prefer to keep out competitors in other ways. That is why the business community, despite its rhetoric, has so often been a major enemy of truly free enterprise.
Milton FriedmanFor example, the supporters of tariffs treat it as self-evident that the creation of jobs is a desirable end, in and of itself, regardless of what the persons employed do. That is clearly wrong. If all we want are jobs, we can create any number--for example, have people dig holes and then fill them up again, or perform other useless tasks. Work is sometimes its own reward. Mostly, however, it is the price we pay to get the things we want. Our real objective is not just jobs but productive jobs--jobs that will mean more goods and services to consume.
