I'm not saying you're wrong, but I'm highly skeptical that one person would be worth, say, $99m more than a very-well-paid engineer, or $50m more than someone too rich to care about money other than as a way of keeping score, in just a few years. Rockstar executives get crazy money even when they run companies into the ground (see Meyer, Marissa) or merely keep them afloat (Tillerson, Rex). I suspect rockstar engineers are getting a bit of the same treatment, which has little to do with differences in performance among those making more than a small multiple of average pay.
