“I got an aviation degree because it used to be the only way you could qualify to become an air traffic controller. The age cutoff is 30 and I graduated when I was 29. Well, they decided to ‘restructure’ the hiring process mere months after I graduated, and they canceled all hiring panels for two years. I aged out, and now I have a useless degree that I still pay student loans on.”
