>So the only sense in which Google "should" pay more isn't a practical one (clearly they pay enough to fill their roles) or a justice one (they're not stealing $500m in value from each employee if their bottom wouldn't much notice any single employee's absence)—it's some sort of argument about an ethereal sense of fairness that says that by merely participating in a system you're entitled to the average per-person output of that system. Which is definitely an ethic, but it's not one I can get behind.
I see where you're coming from but I think you're missing the fact that large projects have lots of bullshit work that requires high skill but is technically lower value. There is a lower bound to what people will accept, as people with marginally better skills get lucky enough to get highly-visible and much more highly compensated roles. The pay stratification you wish for is already built in, and the average just reflects the fact that these companies DO make enough money to have competitive pay rates.
