Boeing is also a major defense contractor, and has facilities spread out across many states. No politician of either party is going to call for the shutdown of a major employer of their constituents and a key component of national security.
seems to me that you might want quality control on those defense/weapon systems. if the rot is this bad in one part of the company like as not it is just as bad on the govenrment contract side as well.
The pressure to cut costs may be a little lower on the government contract side.
Depends on the contracting mechanism. If it's something like cost-plus, there is less pressure. But on fixed cost, it might be just as great.
That’s true but it’s very easy to imagine at least one party being more than willing to have the FAA be less deferential.
why don't they acquire Boeing into a government owned company (for the defense stuff)
The US doesn't do government-owned (except in exceptional circumstances). For one, they would be sued by the shareholders (unfair seizure) and competitors (unfair competition). It also is not clear that the government acquiring something would make it run better.
