Bill Gates is a founder of Microsoft and the world's richest individual.Suppose Microsoft sells more software and Mr. Gates acquires another billion dollars in wealth.
Simultaneously, suppose a burglar whose income is well below average broke into Bill Gates' house and stole a million dollars worth of antiques.
Using the "it's not fair if the rules aren't fair" approach to fairness, is Mr. Gates' acquisition of additional wealth fair? Is the (poor) thief's acquisition fair?
