When Bill Gates started doing his foundation work, I remember him talking about bringing computers to everyone in the world. Then a year later I remember reading a quote from him about how wrong that was. He finally realized that many people don't have basic food and water. Now he seems to be doing some decent things with his life but it took a long time (and a lot of immoral business practices) before he woke up. Better late than never, I guess. While these people certainly understand the business world better than I do, to say they are smarter or more worldly is highly debatable. If you want to use an example of someone that's smart and worldly, pick someone like Nelson Mandela. Not a CEO.
