A man spent nine years paid well below the rate for his trade. He found out in a van, when a younger colleague said the figure out loud.
Nobody had cheated him. Nobody had undervalued him on purpose. He had simply never asked what the number was, and no one had asked on his behalf.
Worth and price drift apart quietly, and the drift is almost never a decision. It happens in the absence of a conversation.
Wanting a specific amount, and being able to say it out loud, is closer to bookkeeping than to greed.
