It's the conceit of capitalism. We've structured our entire society around giving the boardroom class most of the rewards from our societal output, so they've taken that to mean they create most of the value. They are job creators, deliverers of technology, builders of nations, and how it gets done at the low level is an fungible implementation detail. Whether it's slaves or workers or robots down in the fields / mines / factories, the board are the ones driving the ship and therefore doing the real, important work.

And yes, this does mean they view us workers as somewhere between slaves and robots, replicable by a token predictor.
