Did you see the comma. Where after it said, took RISKS that others would not take? Anyone can get a minimum wage job and hold it.
Anyone can go to college no matter your bracket, and do well. Making 30-50 grand a year, and hold that job.
Not everyone will get that steady job after college, and then take a loan out for $100,000 and start their own business that may or may not be successful. Which, if it isn't, would ruin their credit, and completely bankrupt them. That is why people make more money than others.
Oh, and by the way, almost any small business owner works much much harder than any of his employees. Not all, but the majority.
