I agree. I think these things are two sides of the same coin. There's usually some kind publicity required to attain that status, and that ranges from some a little self promotion to braggadocio. Once there's a surplus wealth, power, or fame, most people tend to back off; that feeling of liability sinks in.

There are exceptions, but even among the flamboyant successful (say, Ellison, Branson) there seems to be a trend of lowering one's profile.
