Yet Canada has Interac and India has UPI which nationalize all digital transactions while charging even less. In Europe they’re much more heavily regulated and this charge even less than in the States.
So if within their own industry Visa and Mastercard overcharge like crazy, especially when they can, what makes you so sure that they’re a good counter example for a completely different industry? Especially when competitors seem to be charging a very similar rate for a similar service?
That being said, it is a fair point when you consider that retailers and other similar product middle men tend to charge 1-3%, but it’s important to also consider that Apple position’s itself as a luxury product and brand where 30% markup isn’t actually out of line.
