Some of the most bitter and generally unhappy pilots I've ever met are wide body captains making over 250/ year and work 10 days a month....!
You just have to read some of the usual posts here, people spending a lot of time trying to convince everyone that their airline is so great...! That they are enjoying their careers so much, everything from the layovers to what they feed them during the flight....., at the end is nothing but another performance of the sad clown!
I remember a story of an AA pilot riding on the jumpseat of a UAL pilot back in the 90's, when they were both at the top of the industry payscale ( an 737 F/O made what a SWA Capt made at the time and with a much better retirement). These guys were comparing notes and if one had something the other didn't they thought they were being raped. They were both genuinely stressed out over it.
Sometimes we are own worst enemy.
