74. Richard Kinder
Kinder Morgan, one of the U.S.’S largest energy infrastructure firms with 84,000 miles of pipeline, was cofounded by Kinder in 1997 after he left Enron. He owns more than 10% of the company and serves as its executive chairman. In 2015, his alma mater, the University of Missouri, used his $25 million donation to open the Kinder Institute on Constitutional Democracy.
