"That is why, as Adam Smith put it, an individual who "intends only his own gain" is "led by an invisible hand to promote an end which was no part of… - Milton Friedman

"Hardly any worker today engages in the kind of backbreaking labor that was common a century or so ago and that is still common over most of the globe. Working conditions are better; hours of work are shorter; vacations and other fringe benefits are taken for granted. Earnings are far higher, enabling the ordinary family to achieve a level of living that only the affluent few could earlier enjoy. If Gallup were to conduct a poll asking: "What accounts for the improvement in the lot of the worker?" the most popular answer would very likely be "labor unions," and the next, "government" — though perhaps "no one" or "don't know" or "no opinion" would beat both. Yet the history of the United States and other Western countries over the past two centuries demonstrates that these answers are wrong. During most of the period, unions were of little importance in the United States. As late as 1900, only 3 percent of all workers were members of unions. Even today fewer than one worker in four is a member of a union. Unions were clearly not a major reason for the improvement in the lot of the worker in the United States. Similarly, until the New Deal, regulation of and intervention in economic arrangements by government, and especially central government, were minimal. Government played an essential role by providing a framework for a free market. But direct government action was clearly not the reason for the improvement in the lot of the worker."

Keep your eye on one thing and one thing only: how much government is spending, because that is the true tax. Every budget is balanced. There is no such thing as an unbalanced federal budget. You're paying for it. If you're not paying for it in the form of explicit taxes, you're paying for it indirectly in the form of inflation or in the form of borrowing. The thing that you keep your eye on is what government spends. And the real problem is to hold down government spending as a fraction of our income. And if you do that, you can stop worrying about the deficit.

Nor do the spokesmen for these organizations ever explain why, if the public school system is doing such a splendid job, it needs to fear competition from nongovernmental, competitive schools or, if it isn’t, why anyone should object to its “destruction.
