There is this idea now in this country that all people who succeed, succeed on their own, and all people who fail, fail on their own, whereas neither is true. The vast majority of people in this country stay where they're born. Very few people move too far from home. Rich people rarely become poor, and poor people rarely become rich. But we live in a society ruled by anecdote, so that we have no sense at all of what actually happens to most people.
