The rich do not exist in a vacuum. They need a functioning society around them to sustain their position. Widely unequal societies do not function efficiently, and their economies are neither stable nor sustainable. The evidence from history and from around the modern world is unequivocal: There comes a point when inequality spirals into economic dysfunction for the whole society, and when it does, even the rich pay a steep price.
