Term for fraction of economic value earned? Is there a term for the fraction of economic value earned by a person in their labor that is due to their creation?

Would have a value of 0.1

At the other end of the spectrum, the CEO might be

Economic value created = $2,000,000

Income paid = $1,500,000
