Therein lies the rub. Self-enrichment is a powerful motivator which often times spurs creativity which can not only reduce costs, but can also produce a superior product. It's a rare thing when the government actually does something well or efficiently, so I say lets give private enterprise a try and see what happens. Granted, it's not a sure thing... especially when the government starts messing with requirements and regulations and various inefficient procurement rules (ie, parts must be made in Alabama, assembled in North Dakota, and 47% of the parts must be from minority women owned businesses), but if they can mostly keep their hands off, it might just work.
