I perfectly understand the issue, I work (I might say worked) in a field where - for completely different reasons - the work opportunities are scarce to non existant for senior people, but the question was more about how the sum was quantified.
Being the target of discrimination (be it age, sex, race, religion, whatever) is a terrible experience, but it is not easy to determine the amount of a monetary compensation.
As the parent noted, the $11 M are a rounding error to google, still the amount each person received should not be excessive because google is so big.
I mean, let's say that in an alternate world the amount would be calculated on the gross profits of google and the total amount had been US$ 110 Millions instead (still peanuts).
Would have it been "fair" that each refused applicant got 350,000 US$? (a couple years wage)
Or 3,500,000 each (more like 20 years) would have been adequate?
