I've seen way too many people who actually do know better than their bosses, who actually step up to be responsible, and who are then told to sit down and shut up. I've seen how, after thing go wrong, VP blames their "critics" or "haters" for making them look bad. I think those with knowledge who get punched down, go work for places that give them the mandate first, and then responsibility.

Why work for someone who treats your questions as critiques, and their failures in management as your responsibility to fix?
