Tuner 2, you appear to have a jaundiced view of your peers. Quite a few "4 Eng Captains" are on COM & have worked to get the best possible T's & C's for the fleet that the majority of QF pilots will spend a lot of their career flying despite it having no effect on their own careers. They have not acted selfishly in any way.
The captain that you are referring to has done a lot of research and argued to get the best conditions possible and, no, he has no aspirations to become the AIPA President.
