When someone faces unfairness because they are poor AND because of their race, what idea helps socialists understand how these different types of unfairness combine and make things worse?

The idea that helps socialists understand how unfairness due to poverty and race combine and worsen is intersectionality. Intersectionality is a framework developed to analyze how various social and political identities, such as race, class, gender, and others, overlap and interact to create compounded layers of discrimination or disadvantage. It recognizes that a person's experience of oppression is not simply the sum of their individual oppressions but is a unique experience shaped by the confluence of these identities. For someone who is both poor and of a particular race, intersectionality highlights that they do not just face the difficulties of poverty *and* the difficulties of racial discrimination separately. Instead, these two forms of unfairness interact in ways that create unique and intensified challenges. For instance, a poor person of color might face discrimination in employment that is not solely based on their race, nor solely on their poverty, but a combination where their race makes them a target for lower wages and fewer opportunities, and their poverty makes them less able to access resources or fight such discrimination. This means the systemic disadvantages are not additive but multiplicative, creating a more profound and complex experience of marginalization. Socialists use this concept to understand that policies and struggles addressing only class or only race are insufficient, as they fail to account for the specific, compounded disadvantages faced by individuals at the intersection of multiple oppressed identities.
