Yes, but that's precisely what I mean. If the dollar drops, everything else goes up in both exchange rate terms and PPP terms. Which means that all other things being equal, 1 PPP$ doesn't buy as much today as it did ten years ago, right? So measuring "middle class" by PPP$ rather than by a basket of goods makes more people richer in your statistics without making them able to buy more stuff, right?
