Edit: Ah, the good ol' "reality makes me unhappy so I'll shoot the messenger" down-votes. I don't know why I even comment in any of the Boeing threads anymore.
There's lower hanging political fruit out there.
It sounds like you're suggesting that we shouldn't hold Boeing too accountable because they wouldn't be able to retain or hire as many blue collar workers.
That definitely could be a side effect but I'd be more concerned about creating safe airplanes than safe jobs.
It's a pretty routine argument that says if you threaten my job for any reason I'll vote you out.
Doesn't matter if my job is creating things that crash, giving people cancer, etc.
That argument doesn't fly for a lot of us.
There will still be mechanical and aerospace jobs, just at companies that aren't going to play fast and loose with regulations.
