No justification for stagnant Social Security

To the editor:

My husband and I recently received our Social Security notification for 2016 and as expected there was no increase in the base amount, due we've been told, to low gas prices. There was an increase however, in the cost for our Medicare drug plan, which leaves us not only with not more, but with $13.60 less per month each. In addition, our secondary health insurance is rising by approximately $10 per month.

Can someone please explain to me why those rising costs are not figured into our cost of living Social Security benefits? Congress, with so many benefits, it staggers the imagination.
