No. "Purchasing power parity" fails to take into account a host of tangential & overhead costs. Sounds good to compare what a product costs in two countries in the same currency, and to note the difference in price, but there is so much more affecting those prices even though in "fairness" they should be the "same". <rant> An overstated example... A dozen eggs here may be $2.00, and $0.10 somewhere else, but the former includes: sale in a store clean enough to host surgery in the other country, well-paid staff (staving off their potential poverty), robust packaging, long-term storage facilities, remarkable uniformity of products (each egg almost exactly the same size, shape, and color), proliferation of taxes imposed, long-distance transportation (keeping farming issues out of urban settings), compliance with regulations (starting with: no livestock in residential areas), wages reflecting a very high standard of living (imposed not just by society but by legislation), and quality feed & care of originating chickens; in the other country, the dozen eggs may be delivered in a random box by a guy who has chickens in his back yard and feeds them table scraps. Yeah the same product cost 20x more in the same currency in different countries: there's a radical difference in supply chains, regulations, taxation, and currency flow. </rant>
