It helps Lockheed Martin by preventing 21-year-olds from waltzing into the Pentagon and selling weapon systems to the DoD, allowing them to capture 300× more value than if they were subject to market competition.
Well, this is a requirement that gets passed through to Lockheed Martin and inflates their costs about as much as it inflates the Pentagon's costs. For Lockheed Martin to benefit, they need to be selling on a cost-plus basis, where lower efficiency mechanically means higher profit.
