Proposed Provision: Progressive price indexing (50th percentile) of PIA formula factors for individuals newly eligible for OASI benefits in 2017 through 2056: Create a new bend point at the 50th percentile of the AIME distribution of newly retired workers. Maintain current-law benefit credit for earners at the 50th percentile and below. Reduce the 32 and 15 formula factors above the 50th percentile such that the initial benefit for a worker with AIME equal to the taxable maximum grows by inflation rather than the growth in the SSA average wage index. Disabled workers are: (a) not affected prior to normal retirement age; and (b) subject to a proportional reduction in benefits, based on the worker's years of disability, upon conversion to retired-worker beneficiary status.
