What I took exception to was the assertion, overtly stated, that the rest of us were somehow weak or in the wrong. A little humility goes a long way.
Well, humility will probably be acquired when folks like that transition to the private sector. At my civ job, I volunteer to help with veteran hiring on the side, and also help run the informal veterans' group at my corporate HQ. We have representation up to the O-6(ret) level on the mil side and the F500 Senior VP level by civilian title. As in more than one of the CEO's direct reports, IIRC. The mil rank matrix does not at all line up with seniority on the civ org chart. And literally no one is lording it over anyone else about how long they were in, or how short their stint in uniform was. No one cares.
Folks who can't adopt that mentality will find out real quick that you can come with all the qualifications in the world, but you also have to go back to kindergarten and make sure teacher is putting a "✓" or a "+" on your report card in the "plays well with others" row. I once watched a certain FTS officer preparing to retire, and heard the rumblings behind his back from the SELRES of "yeah, that dickhead isn't getting any referrals out of me."
Edit: I also think this is an artifact of the stack-ranked promotion system. To hit that rank on the AC side especially, your number has to come up over and over and over again, and you need to grind in due-course jobs for literally decades. But I think there's a certain subset of the officer corps that isn't equipped to handle "sustained superior performance." There are definitely humble folks out there who are great leaders and great Americans. But I've also seen folks who rose in rank and all that "EP, EP, EP" started to go to their heads. Humble LTJG flight students who were just happy to be there became arrogant patch-wearers who talked to me like my Dad worse than he himself ever would. Psychologically, the system is set up for our rockstars to be vulnerable to buying their own bullshit.
