I know you are joking, but the funny part is, he most likely is very aware of this. It's not rocket science that the ever-growing apple tax is hurting a once great company at the moment.
Unfortunately, they don't seem to have an option, as the growing tax is clearly there to make up for lack of sales. Which is down to lack of real innovation as of late, they are being outdone by even, shudders, microsoft these days.
So, to keep the stockholders happy, they need to turn up the prices to make up for the lack of organic growth due to market "saturation".
I jumped ship last month, a 5K retina imac, two macbook pros and an macbook air all say left the property, to gether with a couple of iPhone X's. And, what should worry mr. Cook abit about that, is I could easily afford them, it was a move made out of principle. I don't want to fund their lack of new product development.
