How Much Money is a C.E.O Worth?

Six Walmart executives earned a combined $8.4 million in incentive payments in 2013, despite the company’s poor stock performance. William S. Simon, the president and C.E.O. of Walmart’s American operation received total compensation of $13 million. The average hourly worker at Walmart makes $27,000 per year. Is Simon really worth 481 times more than the employees who service the customers who fill the registers with cash? I think not. Please share your opinion.
