What is the rhetorical purpose of the "spoiled-cream" of the woman that the narrator sees as he careens out of the subway in Inivsible Man

As he emerges from the subway onto Lenox Avenue, he is again belched from the whale and thrown into an overwhelming surge of people and things. Enormous light skin women press upon him as one woman did the first time he rode the subway. He calls them "spoiled cream". I think this is a testament to how he sees people differently. The women are no longer above him, they are not cleansed white but "spoiled cream". In this case, he has been reborn as a remade man, one picked clean and mechanized by machines, though these characteristics will surface more fully once he joins the Brotherhood
