Most operational staff are hourly workers who don't get paid anywhere near what a engineer gets and hourly works usually don't get RSUs. You have to consider the 1000s people working on city ops, support, their insurance ops teams are huge, in the US alone they probably have 1 to 2k of people in support roles. Only salaried employees garner the big pay which is guess is less than half the company.

Ps... you'd crap your pants if you knew how many contractors they have doing operations work. Their mostly in low cost counties like the Philippines, and Brazil. Nothing about support scales with growth.

Sure on the other hand employees who got in early have pay packages that are easily in the tens of millions
