In order to free jobs for younger employees from those holding them when they are no longer very productive in today's high-tech environment, the Social Security Admin. should set a mandatory maximum retirement age (MRA) for retirees starting to receive SS benefits and increase the taxable income limit for retirees living on pensions.
This will secure that people who had the chance to be productive allow younger generations to Get a Job in their most productive time of their lives. This will provide fairness in the job market. Retirees can supplement their pensions with part-time jobs.
This is a win-win for everyone.
