"extreme income inequality is rising " you are wrong. Money is causing inflation so even having more money is less powerful than it used to be. Since the cost of experiences are going down because the cost of production is going down and the cost of experiences are becoming cheaper. The world has never been a more fair place. Inequality will always rise with the rise of complexity in a society. This is nature and will always work that way. You are also wrong that greed provides greater return. Since it creates chaos and ruins long term growth. So it's bad business.
