Sustainability discourses are dominated by Western, educated, industrialized, rich and democratic (WEIRD) perspectives. Critics call for remedies to patriarchy, capitalism, and colonialism; and for work that is inclusive of women, non-market influences, and epistemologies of the global South. Focusing on women's work, this paper interrogates the epistemic and practical injustices of geography and gender. The empirical domain is a middle-income economy, offering insight from the space between WEIRD and subsistence extremes. 15 case studies of Malay female micro-entrepreneurs draw on interview, observational and secondary data, tracing the effects of market formalization on market actors. Despite subordinate social status, the women provide reliable income streams for their families. However, their livelihoods are threatened by rapidly formalizing markets. Market formalization crowds out the small and diverse in favor of the large and multinational. To address that problem, a pro-social systems view is required, based on pluralistic conceptions of economies and markets. Drawing on Gibson-Graham's diverse economies perspective we derive 12 propositions supporting sustainable livelihoods. Sustainable livelihoods support quality of life and wellbeing, are embedded in less damaging and more inclusive (vs patriarchal, colonial and capitalistic) provisioning systems, in turn embedded in epistemologies that are reflexively conscious of power dynamics and the WEIRD hegemony. In line with the paradoxes and tensions in sustainability thinking we call for pluralism: Conscious acceptance of all economic approaches, formal and informal, state and non-state, global and local, capitalist and planned; with an emphasis on physical, emotional and social well-being, self-determination, diversity, health, and happiness for the many rather than wealth for the few.
