Bill Gates vs. Larry Ellison

When Gates was a kid, he spent so much time reading that his parents finally forbade him from bringing books to the dinner table. Gates took a break from classes his senior year in high school to do programming with his friend Paul Allen at a power plant in North Bonneville, Washington.

Ellison never finished college. He started out building databases for the CIA. Daughter Megan has financed films such as Zero Dark Thirty and American Hustle; son David produced mainstream movies like The Terminator and Mission: Impossible".
