I guess it could just be that the guy wanted to do something else, something more, than just flying. I know a lot of guys making more than $200K / year flying but still have a business on the side, myself included. Some guys have their own little flying schools, some work extra as instructors for CAE/Flight Safety and other training organizations, some import stuff from china and sell over internet, arrange guided mountain tours, scuba dive instructors etc etc. For myself its not really about the money, it's about working with people, getting involved in something outside flying...
