We analyze the political stability of welfare enhancing privatization of the social security. We consider an economy populated by overlapping generations, who vote on abolishing the funded system and replacing it with the pay-as-you-go scheme, i.e. “unprivatizing” the pension system. We show that even if abolishing the system reduces overall welfare, the distribution of benefits across cohorts along the transition path implies that some ways of “unprivatizing” social security are always politically favored
