Also, more and more of the critical function of the military requires a relatively high level of training and education. We'll always need some in boots to just point and shoot, but more and more it's about drones, theater warfare systems, automatic guidance, piloting highly-technical equipment, etc. The old Swiss system of a few months in the military before college doesn't seem as useful today, when there's such a substantial up-front investment required to turn a civilian into a proficient soldier, in today's high-tech US military.
