It's not even that they have great control over strategy. It's that they can gatekeep the personnel. If you have cray bitches making hiring decisions, you're going to end up with the worst employees.

One thing HR bitches find "disturbing": Confidence. They'll write off the best guy because he seemed like he understood that he was the best. He's "not a team player." Now, men will avoid hiring competition, but they aren't offended purely that someone who knows what they are doing acts the part.

Somewhere there is a CEO of a company that recently became large enough to have an HR department wondering why all the new hires are dopes. I have seen it.
