A bill to amend title II of the Social Security Act to eliminate benefit disparities by increasing primary insurance amounts, in cases where the benefits involved are computed under the present formula (Enacted in 1977), to the extent necessary to assure that such benefits are no less than they would have been if computed under the pre-1977 formula.

Amends title II (Old Age, Survivors and Disability Insurance) of the Social Security Act to increase primary insurance amounts and the maximum amount of benefits payable on the basis of any primary insurance amount under title II to the amounts they would have been under the computation provisions in effect immediately before the enactment of the Social Security Amendments of 1977.
