They are related. The issues in Medicare and Medicaid, and myriad other programs, are rooted in the Social Security system. If you fix the boondoggles in Social Security a lot of downstream issues are going to be affected as well.
SSA has rationalized their patchwork structure and obvious data issues rather than fixing them for a long time. It is not sufficient to say we already know about a given problem as a way of dismissing it. You have to fix it. Each bad record in Social Security is an exploitable weakness, with nobody to complain if fraud occurs.
