It did this in a technical move that is likely to escape the attention of most of the public. The Republican Congress voted to ban any reallocation of Social Security tax revenue between the retirement fund, designated for retirees and survivors, and the disability fund for disabled workers. This matters because the disability fund is projected to face a shortfall some time in 2016. If no steps are taken by that point, workers suffering from cancer, heart disease or other disabling conditions will see their benefits cut by almost 20 percent.
