These people are fundamentally narcissistic and think they personally know not only how the world works, but also how it ought to work. You can see the somewhat innocent version of that in Apple's "you're holding it wrong" fiasco.

That kind of arrogance is kind of normal if you're a very intelligent teenager, since most of the people around you are indeed less intelligent than you, but most people get their reality check pretty soon and grow up. Business ghouls like Larry, however, never got their reality check. They managed to become successful early in life and still operate under that childish mindset.
