How on Earth is this relevant? Whatever your salary is, I guarantee there are people on this planet who could only dream of earning that much. Should you earn less because of that?

So?

Google's corporate culture relies on a high profit margin. The perks, the ability to invest in large bets, all hinge on a high profit margin. If their profit margin shrinks you'll end up loosing the culture. Without the culture, Google would turn into an IBM/Oracle/HP.

Yeah, and value is relative?

Who cares if there’s a consumer staple company with 5% margins out there? Companies are evaluated against their own results and valuation.
