The world changes. Setting aside the officer debate, I would argue that so much of what NCMs learn in just about any tech trade, especially those getting Spec pay is pretty damn close to college level. Look at all the electronics trade that did POET. How would those be different from the 1 yr accelerated electronics programs that colleges or private institutions like Devry offer/ed?
On the officer side, I would argue, it's not the paper, it's the process. Presumably, while getting a degree, one develops faculties like communications and critical thinking and quite frankly maturity. I know people will say that we used to have 20 yr old officers in WW2. That is just hard to do today because society and culture have changed. Maturing that individual before you put them in charge of other humans probably has some value.
