Why do you want those brands to exist?

Some perspectives would say that they serve no real purpose other than performative wealth display and distribution. They appeal to everyone at fundamental psychological levels to "fit in" with a popular trend or "in group".

Their actual quality is often no better than other manufactured goods. It is their perceived quality and style that are the entire reason their brands exist.

(and... I can admit that certain "luxury brands" are definitely appealing to me personally, even if they make little "logical sense" to own - maybe not clothing so much, but... watches...)

The opposite of “Why do you want those brands to die?” is not “Why do you want those brands to exist?”.
