The problems China's rural-born migrants face in accessing urban public services, including education, are widely known. This article analyses how official discourse attributes migrant children's vulnerability to their 'problematic family background' while exhorting them to show 'gratitude' to a benevolent state. Combining documentary analysis and insights from fieldwork, we examine how 'gratitude education' seeks to inculcate notions of a moral hierarchy in which migrants are subordinate or inferior. We further investigate parental beliefs and practices with respect to gratitude, and family participation in related educational activities. The findings indicate that such activities constitute just one aspect of a broader strategy that extends to initiatives focused on governance and philanthropy. Programmes of gratitude education are one tactic for concealing the deficiencies in government action on rural migrants' behalf. By associating entitlement to public goods with individual or familial propriety, they aim to legitimate the institutional barriers that ensure migrants' enduring marginalisation.
