There's an old German short film called Nicht löschbares Feuer (Inextinguishable Fire, 1969)[1] that I'm fond of. It was a protest film against Napalm and how some companies wouldn't really let their employees know what they were actually working on.
"I am a worker and I work in a vacuum cleaner factory. My wife could use a vacuum cleaner. That's why everyday I pick up a piece. At home I try to assemble the vacuum cleaner. But however I try, it always becomes a sub-machine gun.
...
This vacuum cleaner can become a useful weapon. This sub-machine gun can become a useful household appliance.
What we produce it depends on the workers, students, and engineers."

That last line is still very relevant today.
