The $1b per employee large corporation is much easier to imagine though, per the point of the OP - it's hard to imagine someone generating so much revenue that their company is valued at $1b not choosing to hire at least one person to do stuff they haven't got time for or don't like doing.

Well, I don’t see much difference between $1B and $100M, and none of these companies would hire me “to do stuff they haven't got time for or don't like doing.“
