That is easily disproved. A good counterexample is in the book Copy This by Paul Orfalea. He had trouble in school and couldn't hold a job so he started a copy place. This became Kinko's after his nickname and grew large in part because of his systematic way of having employees and customers all treated with respect. When he got tired of the business he sold it to FedEx and shared he five billion with his family.

We need to do something about out of control inequality, such as in the past when we had strong regulations on industry, high taxes on the rich, and pervasive union membership, but lying about what is going on helps no one.
