It's not hard to imagine that all the power elite people you mention were so much more charismatic than you that you "couldn't discriminate more than one level above" your own charisma. That halo effect that Michael Vassar mentioned. Not that they weren't smart and competent but, charisma can be used to make you seem more smart and competent in the same way that I see you as more charismatic than you really are because you are smarter and more competent than me.
