Well, like I mentioned, it doesen't seem to be FASHION or LUXURY world average at all, which is why is asked for gucci and prada, chanel or hermes equivilant info, rather it's conglomerate average, which include General Electrics and Hydro among others. Try to follow the link and look at the numbers.I am sort of disappointed to learn that LVMH spends half the amount of the industry average on labor and material costs...
UNless the OP got the numbers from another source, I'd hate to see a lot of people being disappointed for no reason.
