Where does the money come from?
For service academies, there is federal funding. What does that federal funding get you? School.
I am not aware of any aspect of USCGA, USMA, USNA, USAFA or USMMA that would be SO much more expensive than any other school.
My experience is entirely with USCGA. From my four years at the school, I don't remember anything that was better than many of the other schools I looked at, including nice private colleges.
Chase Hall, our dorm, wasn't anything to brag about. Sure our rooms were a decent size. Our furniture was pretty basic. We didn't (at the time) have A/C. Most of the dorm rooms I called home were built in 1933. Chase Hall wasn't state-of-the-art. My main academic building, Satterlee Hall, wasn't state-of-the-art. Heck, even the ship simulator was older.
We had a small football field, soccer fields, softball and baseball fields, a poor (but now MUCH better outdoor track) and in interestingly sized indoor track. We had half a pool and a good sized pool, both indoor. We had a decent sailhouse and sailboats/crew. Nothing I've listed is any better than our neighbor, Connecticut College, except that they also had a hockey rink.
Our library wasn't horrible, but it wasn't anything to REALLY brag about (although our librarians were helpful).
I'm not complaining about USCGA, I think it was great. All I'm saying is, I have NO idea how the figures at a service academy can be SO much higher than other colleges unless, 1. other colleges are failing to factor in costs that may be harder to calculate but still exist or 2. the academies calculate too many costs.
I go to VMI or the Citadel and, just from a quick walk around, there's nothing that stands out as "more efficient" to me.
So where is this cost coming from? How do you charge someone to go to school, make them serve a number of years after their education is complete, and have them fall under UCMJ.... all at once? Won't happen.
What is cheaper about a SMC that a federal service academy is missing?
