Why is it such a surprise that different kinds of employees are treated differently and receive different perks? If I went to any factory in the US I wouldn't expect to see the janitors being picked up and dropped in limousines, or the housekeeping staff joining in on the company vacations. This isn't exactly the same thing, but it's like complaining that construction workers don't get paid as much as architects and investors.
