Social Security for Seniors not increased enough to keep pace with inflation

A recent news story had some interesting observations about the very low Social Security COLA increases for 2016 and 2017. The annual survey by The Senior Citizens League shows that these increases do not keep pace with the actual cost of living increases of older Americans. This is because the medical and food costs are a higher part of the budget for seniors. The CPI index used to adjust social security is based on all consumer price components. If the CPI for the Elderly (CPI-E) was used social security income would have increased as follows: 2016: 0.6% (actual increase -0-); 2017: 1.5% (actual increase 0.3%). There is apparently a legislative proposal to change to the CPI-E index. However, with all the problems with the expected insolvency of the Social Security program, I can’t imagine that any new bill to increase social security payments would get passed by Congress.
