I feel like you're implying that in order to start a successful business you need to think/talk like this. I can't imagine any reason that would be true. However, if you want people to listen to your theories after you're successful, this type of language is exactly what you should use. He's maximizing his audience. It's proven that this type of speaking works well to build an audience (at least in the United States). In contrast, it's not clear that this way of thinking is required to start a successful business.
