For most of its history, the United States had a ruling majority. But during the late 20th Century, that White caste divided into two groups, which I’ll call Metropolitan Whites and Heartland Whites. They have different interests, so they no longer cooperate, which means each is effectively a large minority. Both benefit from the economic and political advantages of White skin, but the Metropolitan Whites rely on White privilege less because they’re wealthier and more plugged-in to the new economy. That frees them to ally with non-Whites.
