In this article, we consider how zones of slow death can emerge from epistemic marginalization—specifically, the kind that occurs when a social group lacks shared interpretive models due to processes of “social descent.” Drawing on an ethnographic study of waste collectors who moved from skilled to low-skilled or unskilled labor, we explore how this epistemic marginalization is reinforced by the temporal framing of certain lives in the “past tense.” In this way, epistemic marginalization and temporal disqualification are intertwined: denying a group’s interpretive authority simultaneously enables the erasure of their claims to justice as outdated and obsolete.
