In order to understand business you must study the greats, in this case, the giants who created America, and the world after them. These were men who saw things differently than what no one else could. They put their ideas into motion, even if it meant trampling others, in order to create industries that we today take for granted. See how they all did it in this wonderful series that the history channel created.
My recommendation would be to buy the series on DVD, and put together a salon, so that you can discuss what you watched afterwards. That should create a great thought-provoking conversation among like minded business people. A must watch for history and business students.
