Some arguments suggest that their stewardship allows that organization to ultimately achieve its goals and earn its profits, which could be significant.
How would you feel if you and a co-worker both closed deals, only you worked much harder and closed a deal that earned the company twice as much money? Should you both be compensated the same?
Let's stay instead you were promoted to managing the previous group of coworkers. Now your scope of responsibility increases, stress and headaches, and management duties has increased. You are also now earning the company more money because you're good at it. Should your pay be tied to how much you're earning the company? Could you now make double what your subordinates make? More?
In another scenario, you are the most senior manager of an organization. Some of your senior individuals are extremely talented, tenured, and earn the company great deals of revenue because of their skills, people generally like working for them. How easily could those people be replaced, without affecting the organization's success? How long would it take you to replace them? Would the business suffer in the mean time? Could those individuals be easily poached by another organization who pays them more? How much more? What is the overall market price for that individual's skill set? How much education and talent versus replaceability do they have? Ultimately what are they worth?
