Unfair to paint academia like that. My interactions with tenured professors in my dep has been nothing but pleasant. They don't have egos (or don't act like it), are more than happy to help, and have been like a family to me my entire academic career. Don't mean to nitpick, and I know there are academics that are huge pricks and depts that are unfriendly places. But it's not true of them all and I'd hate for people to get that view.
