Isn's this the last 20% of performance being expensive and the last 1% prohibitively so? I imagine for high-end leather, you are raising 10 animals for 1 ending up having skin without any bruises etc.

Speculation: Then, in the end, this explains maybe 1/3 of the pricing, the next 1/3 is marketing (prime real estate in metropolises, extensive sponsoring, one store employee per customer, a doormen, ...) and finally some nice profit margin, looking at you LMVH.
