Serious question for you, the resident naif: What do you, in your completely uninformed, sophomoric, opinion, would happen if all the people in a particular group who are vocally dissatisfied followed your low-effort advice and actually just left? This goes for countries, airlines, whatever. What would happen if all the people who most strongly demand change just left?

I'll tell you before you pull a muscle trying figure it out: You'd be left with an airline comprised of only all the other milquetoast schmucks who are happy to go with the flow, eat what's put on their plate, resign to being second seventh (or is it 8th yet?) best, and then come on to the forums and preach sanctimoniously to anyone with legitimate gripes about how it's their attitude that's the problem.

"Love it or leave it" is and always has been a total fallacy, just like the rest of your post. No, a 1 year upgrade in JFK isn't a good enough reason for someone with seniority here to leave. No, not everyone is able to commute. And NO, I don't expect you to be able to comprehend why it's possible to be dissatisfied and demand better conditions but be unable to simply quit but you should give it a shot.
