CE,
Yes they all have a long list of gimmees from their respective governments.
Boeing benefited from the Military side of things, but still made large bets on the 707 and 747 for civilian use of which both had some $$$ for R&D from the Tanker and Freighter side of things. That funding did have a purpose other than basic welfare.

Original point was that Boeing,McD and Lockheed weren't given the percentage of government handouts to specifically build a jet like the original RJ's and their follow on models received from Brazil and Canada and probably Japan with the MRJ.
