I don't think it's the assembly line people either. It's the management that puts enormous pressure on the engineers and the assembly line people. That results in corners being cut, et voilà!I'd add that I don't think internal operations at the level of the assembly line is the fault of the engineers. They probably dedicated their life's to these planes, and even post design. Engineers remain on call for pilots in real time in case a pilot has an emergency in the air, tower can call an on call engineer at 3 am and they'll answer.
Don't want to be too insulting, but assembly line "people" aren't exaclty engineers and need to be heavily watched over for quality control.That would be my only defense for Boeing.
By definition in this day and age, management are the slaves of the shareholders. They don't care about safety, nor about the well-being of the workers. They only care for dividends (shareholders) and bonuses (management), nothing else.
