While I hold a US passport and live in the US, I can’t claim a background that is solidly from the US. In my experience in the US, location matters and general culture varies (surprisingly) widely. I would find it hard to believe that a skin-color segmentation is effective across the entire population. In my limited experience not in sociology but in running consumer segmentations as a management consultant years back, the idea of a single, best segmentation for all the USA does seem suspect. My personal experience in the US is relatively low in socioeconomic diversity but high in skin-color diversity (lots of educated, well to do people from all over the world who all think more or less similarly). “Race” or specifically European-ancestry versus former slaves is the main, historical dichotomy in the US. But well-to-do “Asians”, various people from the continent of Asia, people from other continents, and mixing tends to dilute the historical dichotomy. But the mindset persists. To me it seems as though skin-color diversity feels good to certain (perhaps many) Americans, but it isn’t necessarily logical. (Editing for typos)
