According to Wikipedia, “creamy layer is a term used in Indian politics to refer to members of a backward class who are highly advanced socially as well as economically and educationally, and not eligible for government-sponsored educational and professional benefit programs.”
What is the etymology of this term? Not being a speaker of Indian English, the words “creamy” and “layer” both strike me as unusual descriptors for classes of people. Is there a connection to the idiom “cream of the crop”?
