If you've been looking for an actuarial study of the effect of eliminating the cap on wages covered by the F.I.C.A. tax and allowing those extra wages to be considered in determining Social Security benefit payments, Social Security's Chief Actuary has you what you need. See the table below but note that the proposal would also change Social Security's COLA to the CPI-E index. The "E" is for elderly. That change would increase the COLA. Eliminate consideration of the additional wage base in benefit computations and stick with the current COLA and the Trust Fund reserves stay in balance almost as far as can be computed.
