I always come back to the cinema image of the rich guy casually tossing the keys of his supercar to the valet. The reason it's "cool" is the effortless balance. He has fun with the car, but he is no petrol-head. To you & I it's an unobtainable thing, to him it's just another car.

That's how I've come to understand it. These wealthy types are not horophiles or sommeliers. They just casually appreciate beautiful craftsmanship & the taste of high quality alcohol- and who doesn't? Just look at how techies love machined metal laptop bodies, and the popularity of craft beer. The reason out-groups are quickly identified is because they cargo-cult the material things.
