something i've also noticed, is that people who are going to complain are typically going to complain anywhere they go...the guy who complains about days off at company A, complains about not flying enough at company B.

I'll agree with what you said though, there's no joy in chasing quick upgrades. However, i believe the same is true about chasing some elusive QOL that seems to always be greener next door. For people who are trying to get on with their ideal company, find a good path to get there and stick to it, but while chasing the quick upgrade can have disasterous effects on a person's future job outlook, and current quality of life. Bouncing around from company to company will do nothing but prolong your time in the minor leagues.
