With respect, it has always been thus.
As infuriating as I find Chang's words and, apparently, attitude, he at least recognizes the 'system' and embraces it.
Big Blue has always had its hoops to jump through, PME almost always being one of them.
That the majority of talent finds the system repugnant doesn't matter to "The Man."
The Man got where he and it is because it willingly jumped through those hoops.
It finds those unwilling to do so as failures and unworthy. Fighting it, while morally satisfying, nearly always results in frustration for the fighter and a win for The Man.
That "two below" and DG in academic situations counts so much for a military, thus warfighting, institution is demeaning but those in power have made/rigged the rules. They won't willingly change those rules and will very willingly cull from the herd those who won't embrace those rules.
That it costs lives each and every time the "warfighting, i.e., bullets flying, things going 'boom,' bit occurs is acceptable to them to maintain the purity of the body.
The AF is not different from any other large organization with its own culture. You either embrace those norms or the body eventually rejects you.
Informed choice is the best any individual can do.
That and being able to look yourself in the mirror...
Nothing cosmic or wise, just recognizing the very well known threat.
