Salaries are a price, just as the price of chocolate is a price. They’re just the price at which someone’s work sells. This is true no matter what your job is or how much you’re being paid--if your wage is the price at which your labor sells, the salary a CEO gets paid is also the price at which his labor sells. So we shouldn't give a different explanation for the wages/salaries of rich people from the explanation we give for the wages/salaries of poor people. All salaries are determined by supply and demand for the labor in question.
