This paper develops an overlapping-generations model including wage inequality within a generation and intra- and intergenerational resource reallocation via social security. Based on the concept of a stationary Markov perfect equilibrium, the paper focuses on the feedback mechanism between current individuals f decisions on saving and future voting on social security. The paper demonstrates the determination of social security via probabilistic voting and its consequence for consumption inequality within a generation. It is shown that when the elderly are politically powerful, (i) the economy attains an oscillatory path of inequality and social security, and (ii) aging may reduce consumption inequality.
