One thing to keep in mind is a lot of engineers don't want to work in management and/or don't have management aspirations. Steve Wozniak is a pretty good example. Personally, I work as a chem/materials engineer if I were to move into a management position I'd have to give up doing technical work and step into a more administrative role and that is something that does not really appeal to me. I think similar thing for politics, there doesn't tend to be many scientist or engineers running for government because that sort of thing isn't very appealing to people like me.
