from the point of view of a marketing major, it's us consumers that allow chanel and all other high-end brands to continue ridiculously jacking up the prices for cheaply made bags because we continue to buy them. We can not be naive and say that these bags are all hand-made in france/italy because it simply is not true. They are a business and as any business would do, they will find any way possible to increase their profit margin if customers are still purchasing and the demand is high.
Realistically, all of us are not paying $6000+ for a bag just because it's "great quality" because you definitely can get "great quality" bags for 1/50 of the price. We are paying these prices for the branding, and chanel and karl lagerfeld has done darn well with their branding for women to want to continue buying these bags for the amount of car down payments. You will never get them to stop the ridiculous price increases on their cheaply-made products unless we stop buying from chanel...but will that really happen?
