And I would add that although some people see Apple's recent lack of innovation as proof that you need an asshole dictator at the top, I take it as proof that putting abusive people on top harms those under them, preventing people from really owning what they're doing or learning to innovate collaboratively.

It's basically "après moi, le déluge" as self-fulfilling prophecy. Real leaders create something that lasts beyond their deaths. Contrast this to George Washington, who could have ended up king but worked hard to make America about institutions, not men. Or, in business we can look at places like Toyota, which have remarkable cultural consistency and continuing innovation across the decades.
