Perhaps I misunderstand you, but I imagine those three companies have minted quite a few IC millionaires (let alone management). But maybe high single-digit millions isn't what you consider to be "really rich", dunno.
Trying to set a threshold for what counts as "really rich" is the reason for the comparison I was asking about. My sense is that the average employee of an investment bank or hedge fund is a lot richer than the average employee of Apple, Facebook, or Google.
