Interesting part of the article:
Although my example pales in comparison, the article reminds me of my career.
I was an enlisted "sweaty" in the Air Force and I had a pretty awesome job...at least in the world of the enlisted. When I finished my BS degree, many thought I should apply to OCS so I could become an officer. My uncle was one of those proponents (he was a former enlisted that later became an officer) and I heard it incessantly from him. Well, odds were that if I went to OCS, I would get to be a supply, intel, or other admin type officer. Sure, the pay (and retirement) would have been more, but the j*bs would have been TERRIBLE. Plus, you add in the politics/longer hours/extra-curricular "fun" that is required in a officer world...yeah, no thanks.
In the end, I am *very* happy in the choice that I made staying an enlisted guy. I continued to have the best j*b in the enlisted world, and for the most part...I only w*rked when I was AT w*rk...no need to deal with BS when I wasn't there. And the retirement pay of this enlisted guy? Plenty enough to retire quite early.
