To take a different example, whether it is less costly for loggers to use a chain saw or handsaw depends on the price of the chain saw and the handsa… - Milton Friedman

In the past century a myth has grown up that free market capitalism—equality of opportunity as we have interpreted that term—increases such inequalities, that it is a system under which the rich exploit the poor. Nothing could be further from the truth. Wherever the free market has been permitted to operate, wherever anything approaching equality of opportunity has existed, the ordinary man has been able to attain levels of living never dreamed of before. Nowhere is the gap between rich and poor wider, nowhere are the rich richer and the poor poorer, than in those societies that do not permit the free market to operate.

"The compulsory attendance laws are the justification for government control over the standards of private schools. But it is far from clear that there is any justification for the compulsory attendance laws themselves. Our own views on this have changed over time. When we first wrote extensively a quarter of a century ago on this subject, we accepted the need for such laws on the ground that "a stable democratic society is impossible without a minimum degree of literacy and knowledge on the part of most citizens."15 We continue to believe that, but research that has been done in the interim on the history of schooling in the United States, the United Kingdom, and other countries has persuaded us that compulsory attendance at schools is not necessary to achieve that minimum standard of literacy and knowledge. As already noted, such research has shown that schooling was well-nigh universal in the United States before attendance was required. In the United Kingdom, schooling was well-nigh universal before either compulsory attendance or government financing of schooling existed. Like most laws, compulsory attendance laws have costs as well as benefits. We no longer believe the benefits justify the costs. We realize that these views on financing and attendance laws will appear to most readers to be extreme. That is why we only state them here to keep the record straight without seeking to support them at length. Instead, we return to the voucher plan — - a much more moderate departure from present practice."

every country, it always is and must be the interest of the great body of the people to buy whatever they want of those who sell it cheapest. The proposition is so very manifest, that it seems ridiculous to take any pains to prove it; nor could it ever have been called in question, had not the interested sophistry of merchants and manufacturers confounded the common sense of mankind. Their interest is, in this respect, directly opposite to that of the great body of the people.
