"Apple Tax"
So many posts complaining about the "Apple Tax". Don't see posts about the "Mercedes", "Patek watch", "Rojas Haute Luxe Parfum", Tesla software upgrade "taxes" although there are complaints about the cost.
Replacing an Audi headlight bulb cost me ~$500. Even more expensive for a Porsche. I believe BMW repairs are even more expensive. A simple gasket for a Kuhn Rikon pressure cooker braiser is $50. People complain about the pricing for premium products upgrades and repairs but don't call it a tax.
Why they think when you buy a premium brand you should pay budget brand pricing for upgrades and repairs is beyond me.
Do you think that the same people would complain (or, complain as loudly), if, rather than the expression "Apple Tax", one used instead "Apple Extra Profit"?
Nevertheless, while I take the point about "premium pricing", (and the ascribed assumptions that go along with the purchase of such goods and services), I also suspect that there is more to this than is covered by your post.
Premium products, by their very nature, tend to be niche products, with a largely self-selecting consumer base.
Personally, I have never minded paying a premium price for a product, good, or service, but for that money, I expect a premium product, and premium customer care.
These days, Apple is a veritable behemoth of a company, enormously wealthy, with a vast global footprint, and - as part of the tech revolution - is now far more influential (and politically and economically powerful) than (mere) premium automobile manufacturers can ever hope to be.
More to the point, I suspect that there is a co-relation with both Apple's global reach, and their (deteriorating) customer care (which used to be superb, and is something I can personally attest to).
Furthermore, nowadays, Apple is a company that no longer even needs its computing arm, and can afford to retain it as a luxury loss-leader, and is no longer defined by its cutting edge R&D in computer development, for other areas (the iPhone, the Apple Watch) are far more profitable.
However, even more to the point, I also strongly suspect that there is a part of Apple's customer base which has never forgiven the company for becoming a global giant, for they loved the days when Apple pandered to them (or marketed to them) on the basis that they were an esoteric elite, the "cool kids", who celebrated - for they recognised - that fusion of form and function that represented Apple design at its best. Sharing that with the less enlightened masses - along with the fact that Apple no longer needs to woo nerds - must be an unsettling experience.
