I had a roommate years ago who made a living selling knockoffs of expensive handbags, but who would occasionally get busted and have his merchandise confiscated. (I personally think it should be legal to sell fakes but that's another story.) Anyway he switched to buy non-branded handbags, of really excellent quality, arguably as good or better than the fashionable ones. His business went well, as far as I know, but he had to sell more units to overcome the branding 'deficiency'.
A skilled stonemason these days might find him or herself doing quite a lot of work for the wealthy, creating buildings that have traditional-style features but are not good or authentic architecture. That doesn't demean the craftsmanship involved (thankfully), and keeps the skills alive, but the end product is more or less waste.
Compare this Louis Vuitton leather briefcase: http://us.louisvuitton.com/eng-us/products/porte-documents-v...
To this Saddleback: http://www.saddlebackleather.com/thin-leather-briefcase
8x the price but the Saddleback likely has quality on par with, if not exceeding, the Louis. Sure, the Louis is probably very well made, but that has nothing to do with the price.
- Hey man, look what a nice new tie I've got! $1500!
- Dude, you're lame. They sell the same for $5k in the shop down the street.
I was being facetious though, playing off the GP comment's mention of museums. I'm a painter and an unsociable one at that.
