There was this one time when Tesla asked for a raise when working for Edison’s company. Probably one of the hugest misjudgments in economics history made by Edison’s business manager Charles Batchelor saying that there are plenty of his kind out there on the market, and he refused to give him a raise. “No, the woods are full of men like [Tesla], I can get any number of them I want for $18 a week.” Tesla wanted a raise from $18 to $25 a week, and guess what, he left.
