I guess it all depends on perspective. I have a few friends over there and the assesment they give me is not even remotely close to what I hear on this forum.
If my goal is to just be a "line pilot", not a manager or anything else, how would I be a threat to a manager. Show up to work, do my job well, collect a paycheck, and go home. If you are not trying to rock the boat or climb the corporate ladder what is the threat?
