My point about Boeing is that these R&D costs are only included in their government contracts. After a period of time, Boeing then uses the advances they've made in producing military aircraft to produce more advanced aircraft for the private sector. In effect, the private sector is getting a discount on their aircraft because Boeing's R&D has already been done through government contracts.
Well, that's true, but you cannot expect Boeing, or anyone, to forget what they learned conducting the R&D and passing those on to the consumer. That's a benefit of doing business. Unless the Government puts a "Proprietary" stamp on it.
It's not the same thing as subsidization, a guarantee to keep them in business.
