Objective: This article identifies how social class differences in undergraduates' relationships with their parents shaped their responses to educational disruptions caused by the COVID-19 pandemic. Background: The mechanisms through which parents transmit class advantages to children are often hidden from view and therefore remain imperfectly understood. This study uses the case of the COVID-19 pandemic to examine how young adults from different social class backgrounds expect, negotiate, and attach meaning to parental support. Method: This study draws from in-depth interviews with 48 Black and White upper-middle and working-class undergraduates from a single elite university, along with 10 of their mothers. Results: Facing pandemic-related disruptions, upper-middle-class students typically sought substantial direction and material assistance from parents. In contrast, working-class students typically assumed more responsibility for their own--and sometimes other family members'--well-being. These classed patterns of "privileged dependence" and "precarious autonomy" were shaped by students' understandings of family members' authority, needs, and responsibilities. Conclusion: Upper-middle-class students' greater dependence on parents functioned as a protective force, enabling them to benefit from parents' material and academic support during the transition to remote instruction. These short-term protections may yield long-term payoffs denied their working-class peers. Beyond the immediate context of the COVID-19 pandemic, the concepts of "privileged dependence" and "precarious autonomy" offer scholars a set of theoretical tools for understanding class inequality in other young adult contexts.
