It's complicated. It seems clear to me that right now a huge number of people want to increase their absolute wealth more than their relative position. People who move from poor countries to rich countries often wind up in a lower percentile in the new country, but are better off in an absolute sense. Relatively few independently wealthy first-worlders move to poor countries to increase their relative wealth (although a handful of people do, admittedly.) This is complicated somewhat by the fact that recent migrants might still have enough connections to their old country that their higher relative position in the old country is more salient to them than their lower relative position in the new country.
