The Birkin bag is nothing but overpriced hype. De Beers operates in the same manner, creating fake demand and spending tremendous sums on marketing to make you think that diamonds are "rare" when in fact they are not.
These bags are made by Chinese immigrants, not by Parisian or Italian "artisans." How do you think the Chinese counterfeiters are able to reproduce exact replicas that are indistinguishable to the naked eye?
Hermes and De Beers get the last laugh because they know that women are so desperate to appear wealthy that these products sell themselves to these low self-esteem trollops.
