Look at this point...How many jobs require years of skill development...Medical Evaluations...Yearly recurrent Training both class work and skill applications...Oral examinations...Potentailly Headline news if done wrong...Risk and liability to human life...My fellow aviators can find more points I'm sure...Only to be told by some that know nothing about commanding in some cases a 200 million dollar machine that they should not be compensated at the extremes that were once in place...When everything works a pilot still makes life and death decisions...If you were on an airplane when "the Poop hits the fan"...How much is your life or families life is worth?...I think all pilots who fly professionaly feel unappreciated when it comes to compensation...There are so many different points to address...Good luck with your research.
