Except the bombardier issue had literally nothing to do with regulation and to claim it did is misleading. That was 100% Trump with his tarriff BS. The FAA and safety regulations played 0 part in it. We could have literally an unregulated airline industry and it wouldn't have changed the bombardier situation.
Without speculating about political motivations, the Bombardier CSeries tariffs were imposed by two Federal regulatory agencies for "unfair competition/dumping". (US International Trade Commission, and the US department of Commerce)
