Oprah posted some great growth numbers early in her career with her TV show.. but if you start from when she reached $1B in 2004 to today, she has a return of 7.63% annually.
If I had to pick, IMO Oprah is more impressive. But it isn't like we're comparing Bill Gates and the owner of the local dry cleaner. Neither is growing like Facebook or Google. These numbers aren't substantially different. Both have subpar returns. After 2004, Oprah--just like Trump--could have earned more money in an index fund.
If we're really looking for business leaders with good growth numbers, it's probably a better idea to turn off the TV and start looking at the people building companies that are actually growing.
