What? No way. Yes, a lot of airline pilots were former military, but I know several people who are airline pilots and did not come from "very rich" families.

Flying is not in any way some kind of high-status luxurious job. It can be grueling, with intensive and continuous training, wacky shifts, very strict rules, lots of time away from family, long stretches of boredom punctuated by moments of sheer terror. You can lose your career over a minor mistake that snowballed into a incident due to factors out of your control. Minor health issue? Need mental help? Better get those fixed in secret or you probably won't fly again.

In my line of work, a major mistake would bring down an internal website at a big company for a little while. An airline pilot's major mistake would kill himself and a hundred-plus people.

I can't fathom why anyone who is rich would want to be an airline pilot. It's a shit-ton of work, stress, and risk for not much reward. You gotta love to fly in order to stick with it. If the rich want to fly, they just do the training and buy a plane, they don't need to do it for a living!
