What generation was handing out those trophies again?
Last time I checked the classes ranged from 55yo to 27yo. Most of those would be late Gen-Xers and that tired trope would only apply to one or two people per class. . This crud is a myth that shows up at every airline, it's a story that leads every time too.
if you have a huge problem with many of the new-hires you fly with, its time for some introspection.
