While the impact of politics and policies on socioeconomic outcomes is widely studied, including poverty reduction, income redistribution, and children’s education, the link with intergenerational socioeconomic mobility has not received much attention. Using data from between 17 and 39 countries, and birth cohorts born between the 1920s and 1970s, this paper assesses how the political and policy climate during one’s formative years is associated with intergenerational persistence of socioeconomic occupational status. Looking at pathways from socioeconomic origin to destination through education, and directly within levels of education, it is shown that egalitarian politics is associated with declining intergenerational persistence of socioeconomic status. However, the associations are not strong and not always consistent. Education forms a channel for equalization, as the equality of opportunity is comparatively high among children raised in a more egalitarian-oriented polity. A liberal, growth-oriented polity is hardly associated with the level of social mobility in societies.
