Thesis advisor: Alyssa W. Goldman / Pandemic mutual aid groups are part of a contemporary mutual aid movement which intends to marry the spontaneous suspension of social boundaries of post-disaster collective action with sustained community-building and social justice. This comparative case study examines how two such radical social change organizations navigate the tension between ideology and the need for resources. Specifically, I ask what strategies organizers deployed in pursuit of their dual mandate, under the banner of ‘solidarity not charity.’ Despite virtually identical philosophies, visions, and circumstances, I find that organizers deployed different resource mobilization strategies to access and generate moral, cultural, and human resources. These strategic differences directly influenced organizational outcomes: One group continued to operate more than two years after organizing, while the other was on an indefinite hiatus. The findings depart from what might be predicted by a longstanding focus on material resources in resource mobilization theory, and support the call for more attention to culture and ideology in resource mobilization scholarship. / Thesis (MA) — Boston College, 2023. / Submitted to: Boston College.
