Economist Dean Baker on the Gang of Six and their plans to cut Social Security:
The elderly cost of living index that shows they experience a higher rate of inflation is an experimental index, not a full price index like the other indexes calculated by BLS. However, it could be a full index if the Gang of Six and the rest of Congress wanted it to be. In other words, if the Gang of Six is really interested in a more accurate cost of living adjustment for Social Security, they can propose legislation that would direct BLS to construct a full elderly index. This would let them know whether it is necessary to raise, lower, or leave along the annual cost of living adjustment, to ensure that Social Security checks keep pace with the cost of living.
However the Gang of Six shows no interest in going this route. The only possible conclusion is that the Gang of Six is scared of what a full elderly index might show. In short, the gang of six is scared of the information. They obviously have made the decision to cut Social Security and they are not going to let evidence stand in the way.
