Boeing is for sure a shit show and terribly managed, but I don’t think they would blatantly kill guys like that. I think it’s far more likely that the first guy did kill himself because he figured everybody would think Boeing whacked him and that would do far more damage to the company than his testimony would. Now any news falls under a suspicious gaze and here we are thinking some other guys unfortunate death is due to nefarious deeds.
Or I’m wrong and Boeing has a CIA division ¯\_(ツ)_/¯
That’s nothing compared to some of the examples you could’ve given, ranging from various corporations contracting with Pinkertons to attack trade unions, to Coca-Cola assassinating union leaders, to Chiquita and Dole’s various atrocities in central America (which is where the term “banana republic” came from) that included fielding private armies and engaging in multiple coups d’etat.
A lot of those examples are murdering foreign nationals, which is far less likely to get them in trouble with US law enforcement. But you’re absolutely right: trying to make an exhaustive list of proven cases of corporations killing or knowingly allowing preventable deaths in favor of profit would require more of a book than a Lemmy comment.
