Simply stated, “poor people and people of color,” as well as its variants, imply that being poor is like being non-white. Now, if being poor is, in fact, like being non-white, then poor white people are like people of color. Significantly, if poor white people are like people of color, then the concept of white privilege becomes a bit misleading, if not altogether inaccurate. As Part II explains, white privilege refers to advantages that white people are supposed to receive by virtue of the fact that they are white. The concept presupposes that all white people–even the poor ones–have privileges on account of their race. However, if being poor is like being non-white, and if poor white people are like people of color, then it may not make sense to conceptualize poor white people as being privileged relative to people of color. If poor white people’s class disadvantage puts them in a social position that is similar to that occupied by people of color, then white privilege may not be something that they enjoy. Further, if white privilege is not enjoyed by poor white people, then it may make little sense to call it white privilege– inasmuch as white privilege implies that the privilege flows from being a member of the white race. It may make more sense to admit the error involved in the concept of white privilege and come up with a different concept altogether–something like affluent white people’s privilege or white class privilege.
