That's ridiculous. Business owners know well that their job is totally dependent upon doing something of value for others. Employees know well that their job is totally dependent upon benefiting their bosses. Ergo, everyone's job is (and is known to be) primarily measured by benefiting others. The devil is in the details with regard to who those other beneficiaries are, but they are never solely oneself, else it ceases to be a job rather quickly.
