I tend to agree with you. I was generalising quite a bit for the sake of conciseness (& being a little cheeky) Its not uncommon to see people in these roles because of nepotism, they write the checks or they are good at short term games (machiavellian, gift of the gab, office politics). That said, such exceptions tend to not last long because of the unstable nature of these situations. In other words, those who match the description I made earlier tend to eat these peoples lunch given enough time.
