The basic problem of social organization is how to co-ordinate the economic activities of large numbers of people. - Milton Friedman

People forget the fundamental distinction between Adam Smith's version of The Invisible Hand and what I suppose you could regard as Bastiat's version. The French idea was that there is somehow a harmony in nature so that by natural forces if people were left free to pursue their own interests they would benefit everybody. Adam Smith's was a much more subtle and sophisticated argument, that it is possible to set up institutions under which people pursuing their own interests will benefit everybody. His invisible hand required the right set of institutions and I think that's the case. After all, the distinction between a collectivist society and a market or individualist society is not whether people pursue their own interests. If I take Russia, for example, the people in Russia are all pursuing their own interests but the institutions set up in Russia make what is in each person's own interest different from what it would be in the United States or in Britain.

Every special group around the country tries to get its hands on whatever bits and pieces it can. The result is that there is hardly an issue on which government is not on both sides. For example, in one massive building in Washington some government employees are working full-time trying to devise and implement plans to spend our money to discourage us from smoking cigarettes. In another massive building, perhaps miles away from the first, other employees, equally dedicated, equally hard-working, are working full-time spending our money to subsidize farmers to grow tobacco.

The great virtue of a free market system is that it does not care what color people are; it does not care what their religion is; it only cares whether they can produce something you want to buy. It is the most effective system we have discovered to enable people who hate one another to deal with one another and help one another.
