I don't think you have to necessarily be that influential to have at least part of the same power. In other words, I suspect there are mini-Jobs all over the place. The sad part is I think you can get a long way without much influence at all, as what keeps people around isn't how influential or amazing you are, but how much they perceive you to be, and some people are finely tuned producers of bullshit.
