Working in a corporate environment for 10+ years I can say I’ve never seen a case where large productivity gains turned into the same people producing even more. It’s always fewer people doing the same amount of work. Desired outputs are driven less by efficiency and more by demand.

Let’s say Ford found a way to produce F150s twice as fast. They’re not going to produce twice as many, they’ll produce the same amount and find a way to pocket the savings without benefiting workers or consumers at all. That’s actually what they’re obligated to do, appease shareholders first.
