Adam Smith points out that practical things that we use every day often have little or no value in exchange. Things like cups, utensils, socks, and water are a few examples. On the other hand, things that often have the greatest value in the market have little or no practical use. This is because of marginal utility and scarcity . There is plenty of water in most parts of the world (not scarce), which means that, as consumers, we usually have a low marginal utility for water. In a typical situation, we aren't willing to pay a lot of money for one more drink of water. Diamonds, however, are scarce. Because they are harder to find and attain, our marginal utility (additional satisfaction), for adding a diamond to our collection is much higher than someone offering us one more drink of water.
