Apple has ~30% margin, so they will just increase prices. If real SHTF with sales (since iphone 16 has had lukewarm sales already and they have 0 new shocking transformative products), they can start chipping down that part, but its a long way to go to reach competition.

Who pays for all this, as always, is common people, getting poorer. More specifically middle class, poor don't buy money-making devices from ie Apple, and rich will either stay rich or get richer if positioned well.
