When a group of people get together to create something of value in a venture we call a 'business' who decides which person gets which proportion of the profits? The people who did the work? The person who provided much of the wealth as an investment and took risk? Why is 'risking money' worth so much more than hard work? Because people with money to risk have decided that it should be, and they make the rules. Currently whoever happens to be at the top of the business structure decides as a dictator who gets what, subject to some regulations libertarians would like to destroy like minimum wage which assure he does not steal everything his employees have created.
