At the number nine spot is Drayton McLane, owner of the Houston Astros and Chairman and CEO of the McLane Group and a net worth of $1.3 billion. After growing his father’s business at a rate of 30 percent for over fours decades he was able to grow his company’s annual revenue to over $6 billion before he merged with Wal-Mart. McLane has gained a reputation of being an entrepreneur cut from the finest cloth. A risk-taker in the classic sense, McLane’s aggressive business style is balanced with the fact that he’s one of the nicest men you will ever meet.
