While growing fiscal pressures and increasing life expectancy have prompted calls to raiseretirement ages so that lifetime benefits would be concentrated in older ages, some fear that this change -- without other adjustments -- might harm long-career, lower-wage workers. Tying retirement benefit eligibility to years of service might protect lower-wage workers if they tend to start their careers relatively early and work more years prior to retirement than higher-wage workers.
