Honestly, the point I was trying to make was that at the tactical level, a working knowledge of higher level policy and IR, etc... (think H.S. Civics versus B.S. in PolySci) is much more beneficial than some high level, in-depth Masters in International Relations.
This is where we differ. I think the implied assumption is that a M.S. is more of the same B.S., to excuse the pun. It isn't. The content of most liberal arts B.S/B.A programs is very abstract and generally not very applicable to any job.
But in both disciplines I've experienced firsthand (Math and IR/IA/Security Studies; whatever you care to call it), the Master's programs are very practical and designed to send the student out with skills directly applicable to their field of work - it isn't just a stepping stone to a doctorate, which is a different can of worms.
Nobody with just four years of work experience is going to be an uber-diplomat or entrusted with that sort of responsibility(which was about the average level for the Master's students). But I will wager that in the International Security arena, across that strata of people with 4-8 years work experience, whether they be in State, the military, a thinktank, or the UN, the person with the most influence is that grunt Captain, particularly the Marine.
I recall looking around at my classmates, most of whom would return to pencil-pushing jobs writing reports, hoping to influence their superiors with the decision-making authority. And I realized the one person in the room who'd actually be able to go back out and employ the lessons we were learning, was the Army Captain. And then arriving at TBS and seeing how we're trying to duplicate that sort of practical education ad-hoc at every level, it's a shame we're not utilizing assets that already exist.
I agree that there are other, more pressing concerns for a CGO, and time is a huge problem. Of course the wing side is a whole different beast. But I think there's a lot of illusions being held about the utility and purpose of a Master's that are biasing the cost-benefit calculation.
