Valid question. I'll clear about $120k this year. I had 22 days off in June and 22 off again in July. Other months I average 15 days off. I live an easy drive from my base (no commuting).
I get frustrated at work sometimes, but then I hear pilots from the legacy carriers griping about a lot of the same stuff. I worked many other jobs before I finally made it to the airlines. Believe me, you can do a lot worse.
Would I do it again? In the same situation with the same information I think I would make the same decision. I've seen more than a few pilots make their lives miserable chasing dollars. Each of us has to find the balance that works for them. What's right for me, may not be right for you. Sometimes less is more.
That is a pretty good summary of why a lot of people stay.
