André Masson proposes replacing Gary Becker’s “theory” of generational altruism with a structural explanation inspired by Marcel Mauss’s famous essay The Gift: Forms and Functions of Exchange in Archaic Societies (1923), which was rooted in indirect reciprocities between three generations. Masson thereby elaborates a gentle critique of the moral principles often lying beneath the analyses of liberal economists (such as the “demonstration effect,” disen-franchisement, or the theory of homo reciprocans). Accepting the ambitions of economic science, Masson nonetheless maintains a conception of the social sciences that is more competitive than cooperative and provides convincing analysis of the economic and social foundations of current intergenerational transfers. The argument developed in this critical note proposes both a historical reading of the ideology of intergenerational equity, which is only conceivable in the transition from the Trente Glorieuses to the Trente Piteuses, and a structural reading arguing that, for the wealthy classes during the European Old Regime, successful transfers of wealth between generations followed the same formal requirements as those in the twenty-first century.
