Sure, few people may describe those jobs as a living nightmare, but most people have no first hand experience at working any of those jobs.
I'd never want to do any of those jobs, all three of them have positively awful working conditions, with the last usually resulting in lifelong mental damage from repeated jarring of the head (in addition to injuries), and most school districts & airlines push their teachers and pilots to the edge of the law, whether it be student load (and putting special needs students in classes with overloaded teachers illegally), or leaning on pilots to fly with the absolute minimum fuel they can get by with, despite regulations.
... do you have any firsthand experience working those jobs? I happen to know a number of pilots for major airlines and it's probably one of the nicest middle-upper class jobs you can get (assuming you can handle the responsibility).
> leaning on pilots to fly with the absolute minimum fuel they can get by with, despite regulations
You mean, asking pilots to use the minimum amount of fuel that is safe. Do you have any evidence that a major airline has ever pressured pilots to use less fuel than the (generous) regulated minimum?
