> Apple users are, on average, much wealthier... That someone willing to pay for a premium product is likely to be wealthy is a reasonable conjecture for items where the item is so expensive that a typical middle-class customer is making a substantial sacrifice to purchase, if they can do so at all. So for architect-designed homes, small-volume luxury cars, cigarette boats, personal jets... Absolutely. Middle-class people can and do buy small-volume luxury cars, but it's a big compromise and most of the people driving Bentleys are actually wealthy. iPhones are not that kind of luxury item, they're what we might call "affordable luxuries." Even the most tricked-out iPhone is within reach of your typical 9-5 full-time employee if they want one. Other "affordable luxuries" include things like premium alcoholic drinks, expensive basketball shoes, carbon bicycles, and Fashion brands such as Polo Ralph Lauren that specialize in pretending to be exclusive but distributing their wares in department stores. Owning an affordable luxury in no way suggests you're significantly wealthier than people who buy an affordable substitute for the same product. It's more about signalling taste than means.
