No one can earn a billion. You only get that rich by being in the right position to siphon off money from the work of others. If you make a great inventions, its still the thousands of employees doing the actual work, you are just in the right position to take a bit from each and get really rich. If you invest your money, you are in the right position to set the terms, and you will choose terms that even after accounting for the risk and opportunity costs and so on some additional money ends up in your wallet. So even if everyone could live well because the amount of money siphoned away is not to much, there would still be some unfairness in the system that I would want to see go away.
