>>1992301It is not entirely unfeasible that Boeing gets forced out of the commercial space. I would say its likely that they are morally irredeemable and will not be able to ever operate again out of goodwill. Their greed and maliciousness occasionally can find self-interested excuses to pursue quality and safety, but overall they will always be looking to cut corners and put people's lives in jeopardy to make a little more money. They shouldn't be allowed in the airspace of a country with a self-respecting regulatory agency, but the fact is the risk is tolerated because the alternative is a complete breakdown of a crucial utility industry.
And if they actually had to face the consequences of the full breadth of their malfeasance (murdering a whistleblower was bold to say the least) Boeing would disappear completely.
BUT, in the very rare event Boeing is allowed to die its deserved death, whatever steps up to compete with Airbus will simply be a revived or new American firm that inherits the US airliner manufacturing capacity. Brazil, China, Indonesia etc. they are not going to be making widebody airliners that can actually compete with Airbus in our lifetimes. Brazil could probably outdo Boeing, but that still leaves a lot of room between "better than Boeing" and "acceptable" that still isn't up to a 21st century standard.
