Probably because more then half of their employees work retail (I think).
The article says Apple has 383 stores. The smallest store in my area (I would imagine one of their smallest anywhere) has around 100 employees. Even if the average is 100 that means that more than half of Apple's 60,400 employees make retail wages.
Beyond having lower hour-per-hour wages there are plenty of part-time employees.
One better way to compare contributions would be total employee dollars contributed vs total employee dollars paid in wages.
