There are some interesting theories about the ethics in the luxury market.
Wrist watches that cost thousands of dollars are a luxury goods, there is nothing bad, fair or ethical about this business and the market around it.
There are only nice timepieces and there is interest about getting them.
Scarcity of offer, high demand and high costs are the key points of luxury. It’s understandable that somebody might not like the game, but you are not forced to play!
You can get a swatch instead of a Snoopy 50.
A Michael Kors bag instead of a Hermès birkin.
And a very fine Subaru instead of a Ferrari.
You can get them now, without a waiting list, a deposit, a relation with the dealer, and they will serve the function.
Luxury is not for everybody, and by definition is not ethical... because It is superfluous, pricey, and challenging to get.
