The trick to the utilitarian calculation is to include the externalities of all the work he's putting in -- an engineer's salary is only a subset of the value they create for the company.

The question is really how do you count all that excess "value", and is it good-value or evil-value. Once upon a time, the culture over there explicitly stated that they didn't want it to be evil... the bikeshedding going on here is opinions about the current implications of it all.
