I guess if your ego requires you to be addressed as Capt. Van Commander, that would be important to you.

There's a plethora of pilots in the Majors who are very happy to spend their career in the right seat of a widebody. Pay is adequate and they never have to go commuting to chase an upgrade on a narrow body and sit reserve.

You have a point...if upgrade is the key to your happiness. QOL, days off and preferred routes is what does it for a whole lot of pilots.
