"In the United States, the CEO of a large public company makes about 100 times as much as the average person.  Basketball players make about 128 times as much, and baseball players 72 times as much. Editorials quote this kind of statistic with horror. But I have no trouble imagining that one person could be 100 times as productive as another. In ancient Rome the price of slaves varied by a factor of 50 depending on their skills.  And that’s without considering motivation, or the extra leverage in productivity that you can get from modern technology."
