While you are correct in principle, if we were talking about taxing, e.g. cars that sold for over 100 000 dollars, it would be silly to argue that it was hurting the homeless more than rich people (I am ignoring potential side-effects of the tax with respect to employment, etc. here, so I'm oversimplifying massively, but I contend that the rough outline of my point is legitimate). That said, I will immediately concede that the iPhone falls into a somewhat different price bracket than that.
