> Now they cost a lot because brands spend a lot on advertising and use tricks to limit supply, and what the buyer gets in return is an expensive status symbol.
Sounds a hell of a lot like the diamond industry. Also, the top fashion houses, but both industries are taking a drubbing from artificial competition (artificial diamonds, and knockoffs, of various stripes).
I'm a believer in branding. I worked for many years, for a company with a "top-shelf" brand, and saw what it took, to maintain. But it takes a huge amount of discipline and "silly" stuff. Brand damage can come from a million different directions. I have found very few people are willing to do what it takes to maintain a top brand.
For quite a while, there have been "brand-only" products, like Von Dutch, or Life Is Good™. They are the two-dollar hat, with the twenty-dollar logo. Like Izod Lacoste or Members Only, in the last century.
