Scott Adams on the same subject, the morning after your post:

fairness isn't a real thing. It's just a psychological phenomenon that is easily manipulated.

To demonstrate my point that fairness is about psychology and not the objective world, I'll ask you two questions and I'd like you to give me the first answer that feels "fair" to you. Don't read the other comments until you have your answer in your head.

Here are the questions:

A retired businessman is worth one billion dollars. Thanks to his expensive lifestyle and hobbies, his money supports a number of people, such as his chauffeur, personal assistant, etc. Please answer these two questions:

1. How many jobs does a typical retired billionaire (with one billion in assets) support just to service his lifestyle? Give me your best guess.

2. How many jobs should a retired billionaire (with one billion in assets) create for you to feel he has done enough for society such that his taxes should not go up? Is ten jobs enough? Twenty?
