Family wealth and cross-generational wealth accumulation have recently interested scholars across the social sciences. Debates concerning the economic role of the wealthy now commonly recognise that one dynamic supporting economic inequalities is wealth accumulation across generations. To understand the social dynamics through which dynastic family wealth has managed to persist, this article analyses the social meanings that members of wealthy families attach to their wealth and how these meanings contribute to their class-making. Drawing from 26 in-depth interviews with members of super-rich Finnish families, the article analyses how a dynastic class is actively made and supported by specific social meanings and practices that the inheritors attach to their wealth. By exploring how wealthy heirs produce social meanings and practices that facilitate their wealth accumulation and reproduction as a class, the article contributes to recent interest in elites and social class.
