I think the person you're replying to is perfectly aware of the correlation, considering it was a primary feature of their comment.

Not really? The main point of their comment is that companies could be much smaller based on their experience at a much smaller company.

I'm implying that big companies couldn't make as much money as they do without all the employees they have.

Their last para seems to acknowledge the correlation, but flips your assumed causal direction. I.e. they seem to be implying that the that excess money causes the complexity.
