What's interesting to me here is that in the period 2013-2023, only E&Y, KPMG and McK of the "great eight" moved up or down in the ranking, and they only moved around in the 4 through 6 spots by tiny revenue amounts. Maybe that was a max scale decision on the part of those companies' management. On the other hand, I'd love to know the yield per employee. That would be an interesting read.
