Seniors have a higher rate of inflation than any other Americans. Needs for medical, prescription, fuel, and basic living are more important at this stage of life. Chained CPI would reduce cost of living adjustments. Equivically, this would be like losing 17 weeks of food per year.
Chained CPI is not necessary for reducing the debt/deficit. Social Security does not add to the debt/defict, and should not be reduced in order to make up for the debt/defict. Furthermore, Chained CPI will only add two years to the life of the Social Security trust fund.
Better alternatives:
.Requiring ALL Americans (including those making over $112K/yr.) to pay into Soc. Security (will add 75 years to trust fund).
.Tax Wall Street 3 cents per $100 trade (will raise $35 billion/year in revenues).
