True, if you like your job and are happy why would it be necessary to try to convince others that your job is better than theirs? Shouldn't being happy with what you have be good enough? If you like your job at DAL or SW or wherever fantastic, it's great to have a job that you like.
I wonder of engineers, accountants, doctors, lawyers, cops, firefighters, garbage collectors or whatever spend their time on computer message boards bragging that their employer is better than the other guy's? Would you have a conversation like this in person with another professional pilot? Hey Joe, my job at ABC is way better than what your job at XYZ. I fly this kind of airplane to here and there and you fly that kind of airplane from there to here. My job is the best, I'm glad I don't do what you do, why would anyone want to do that when you can do what I do? My company is the best and my job is the best! Seriously, have you ever heard a conversation like that face to face?
