Now that I can see the site, these are all books by people who through a combination of luck, timing, skill, and work managed to get rich. Now they think they figured out something others didn't. No, they were well-positioned--largely through the circumstances of their birth--got lucky, and then had the skill to take advantage of the combination. Now they think they discovered something. They didn't, and they actually have no awareness of how they ended up where they are.
