Excavating Race-Based Disadvantage Among Class-Privileged People Of Color, Khiara Bridges Jan 2018

Excavating Race-Based Disadvantage Among Class-Privileged People Of Color, Khiara Bridges

Faculty Scholarship

The aim of this article is to begin to theorize the fraught space within which class-privileged racial minorities exist — the disadvantage within their privilege. The article posits that the invisibility of the racial subordination of wealthier people of color (that is, their marginalization on account of their race) is fertile soil for the germination of post-racialism — the sense that we, as a nation, have overcome our racial problems. The dramatic visibility of the minority poor’s suffering, combined with the relative invisibility of the suffering of those minorities who are not poor, breeds the belief that class is now …
