Out of curiosity I took a quick look at how much Net Revenue is generated by an individual employee across GS, MS, Google, and Apple.
--GS net revenue per employee is about ~50% lower than google and ~40% lower than apple.
--MS net revenue per employee is about ~30% lower than google and ~20% lower than apple.
Most recent quarter net revenues were annualized and compared to total employees -- full-time, temps, part-time. Net interest income was included for GS and MS, and excluded for Google and Apple (non-operating, not truly driven by employees).
