In reality, cities and countries that are more diverse are more prosperous than homogeneous ones, and that often means higher wages for native-born citizens. Yet the perception that out-groups gain at in-groups’ expense persists. And that view seems to be reflexive. Merely reminding whites that the Census Bureau has said the United States will be a “majority minority” country by 2042, as one Northwestern University experiment showed, increased their anti-minority bias and their preference for being around other whites. In another experiment, the reminder made whites more politically conservative as well.
