It’s not a money thing. It’s a shortage of people who are mentally able to do the job mixed with terrible hours and early forced retirements. ATC school has a failure rate of over 50 percent.
Why not both? If it paid better then more people would apply to ATC school.
It's partially a money thing. ATC is under-compensated. They'd get more - and more talented - people interested if the money made up for the stress, hours, and early forced retirement.
