In an era of intergenerational inequality and political polarization, what might make older voters support greater government spending on the young? Building on literature concerning family-centric political preferences, we theorize that older voters support pro-youth policies and vote for pro-youth parties when they perceive younger relatives to be struggling financially due to emotional bonds and shared risks. Using a large, original survey of British adults, we find that negative evaluations of the financial wellbeing of one’s younger relatives – which are linked to their objective economic assets – are associated with support and prioritization of state investment in education, childcare and housing. They are also associated with opposition to the incumbent Conservatives, in a relationship mediated by assessments that this party represents young people badly. The implications are important for understanding how emotional connections, more than self-interest, sensitize voters to family-wide economic hardship and help produce ‘family-centric’ economic voting.
