This is exactly it. The actual landed cost is 1/10th of the sales price, and most of the rest of the margin pads the marketing and exclusivity machine. If for instance LV starts selling their $200-landed Neverfull bags at $500 or even $1,000, all the infrastructure sustaining the image becomes unsustainable.

Related note: aren't Louis Vuitton bags being made so crap nowadays that even their own anti-counterfeiting staff can't tell what's real and what's not? I remember hearing of someone who made wallets out of discarded LV bags and got harassed for it by the company.

My personal opinion is that the business model of selling status items - specifically those which only have status because of an artificially limited supply they control - is inherently predatory and should be restricted. Not because I'm the morality police and want to stop people from buying a bag that says "I spent $2000 on a bag", but because there is nothing that stops the company from cost-reducing that to oblivion. If you are going to sell a $2,000 bag, it should be marketed on quality, not a cult.
