You don't think so, huh? What decade are you living in again?

I'm not sure if people are being willfully obtuse or actually misunderstanding my point. Every day I meet extremely smart, capable people who are perfectly functional after grueling trips in Y. Maybe J travel is considered the standard in certain industries, but it is by no means a "necessity." If all airlines did away with premium cabins tomorrow, sales reps and managers wouldn't cease to sell and manage. Things would get done pretty much like they always have, albeit less comfortably for those doing it.
