These books are designed to generate more income for the millionaire or to help them become a millionaire...as in they may not be worth that much to begin with. I have read soem books that compares millionaires, their not "how to books" per se, they simply evaluate what these people do. Example, the average millionaire drives a practical vehicle...most own a ford truck. They have multiple income streams and send their kids to Junior or regular college vs private and ivory schools. They live below their income instead of on or above it. Anyhow, I found it interesting, better than how to books.
