Not really. How much money is the HR rep bringing in by hiring/firing people? How much is the person who cleans floors bringing to the company? Customer service reps? etc. The answer is none. They don't directly increase the store's or company's income by doing their job, they simply allowing the business to operate. Salesmen are really the only position that provides direct income for the company, some work off of commission and others do not.
There are plenty of factors that dictate wages such as importance, difficulty, required qualifications, and proven performance.
