I think GP meant that they might give more of a fuck (in the wrong direction) if sabotaging "just this one bolt" means this they can own a significant chunk of stock in the company they are part of.
According to a quick search Boeing has a market cap of ~150 billion and 150k employees, so if you manage to hide that it was you who installed the bolt wrong then assuming the company gets distributed roughly equally among employees then that's a quick 1 million payday. How certain are you that "hopelessly alienated" employees wouldn't sell out a few hundred anonymous passengers for a million bucks?
