Recently I donated money to the establishment of the Muhammad Ali Foundation in Louisville. I regard that as a kind of payback. He smoothed the way for us. He wasn’t just a great person who had conviction, but made the sport of boxing great. He was the first superstar, he made our stock rise. Without him we wouldn’t have earned so much. Americans from every walk of life have contributed to the foundation: Bill Clinton, Angelina Jolie, Brad Pitt. Unfortunately I was the only American athlete to make a donation. There’s not enough respect in our business.
