an excerpt from Raj Patel's "The Value of Nothing: How to reshape market society and redefine democracy":
Over 1.4 million of Ayn Rand's books have been given away to American high schools by the institute that bears her name - the books are free to any teacher prepared to make their students suffer them. Her work is taught as sort of Adam Smith Lite, an entry-level text in support of the free market that finds its most articulate and subtle formulations in the works of the great Scottish philosopher. This is unfair to Smith.
While Rand spun tedious rationalizations for selfish behavior, Smith was very far from a praise-singer for unfettered markets. The term with which his name is most singularly associated, "the invisible hand," appears just once in
The Wealth of Nations. When it does, it isn't used to describe the beneficent effect of free markets at all. The invisible hand is the guiding force that makes Scottish investors behave parochially, preferring to put their money into the Scottish economy rather than investing abroad. By investing in their local economy, investors get a return, of course, but so does the society in which they invest and, because the live there, investors enjoy the economic stimulus too. This is the beneficial yet unintended consequence of investors' selfish motives, and it only comes about because of a preference for domestic over international investment. Not exactly the policy that people who quote Smith are usually in the business of advocating when they talk about the invisible hand.
Smith was a far more subtle and complex thinker than his free-markets-rule caricature, holding sophisticated views on many of the issues that tax modern economics. His opinion on whether money could buy happiness, for instance, was that it couldn't.: "In ease of body and peace of mind, all the different ranks of life are nearly upon a level." He also thought that a primary animating principle behind economic activity was vanity. People worked in order to pay for things that held the esteem of one's peers. This keeping-up-with-the-Joneses, where everyone works ever harder to stay where they are in the eyes of their society, is today's "hedonic treadmill." But it is in his understanding of value that Smith and his descendants have most to teach us today.

The word value ... has two different meanings, and sometimes expresses the utility of some particular object, and sometimes the power of purchasing other goods which the possession of that object conveys. The one may be called "value in use"; the other, "value in exchange." The things which have the greatest value in use have frequently little or no value in exchange; and, on the contrary, those which have the greatest value in exchange have little or no value in use. Nothing is more useful than water, but it will scarce purchase anything; scarce anything can be had in exchange for it. A diamond, on the contrary, has scarce any value in use; but a very great quantity of other goods may frequently be had in exchange for it.
