Most important, if Social Security does not maintain the large retirement trust fund surplus currently projected for the next 30 years, alternative scenarios for return to pay-as-you-go finance differ dramatically in the taxes, benefits, transfers,^and real rates of return that can be offered to different birth cohorts. The implications of cutting taxes, raising benefits or diverting the surplus to other purposes have dramatic impact on the overal
