The great lesson in microeconomics is to discriminate between when technology is going to help you and when it's going to kill you. And most people do not get this straight in their heads. But a fellow like Buffett does. For example, when we were in the textile business, which is a terrible commodity business, we were making low-end textiles-which are a real commodity product.

A few public hangings will really change behavior. One of our Presidents said if he could execute three people each year for no cause, it would make it a lot easier to govern. When someone said that's not enough, he said, "Oh yes it is, because I'd publish the list of people under consideration."

The investment game always involves considering both quality and price, and the trick is to get more quality than you pay for in price. It's just that simple.
