WRONG: the amount we pay into SS goes to fund the Federal deficit and is replaced with IOU's. They don't track how the funds are distributed, but rather, how much you will be owed based on what you paid into the fund.
Like I said, Signalman already paid into the fund. Others are not paying for his benefits.
The amount Signalman paid into the fund has been long spent, so his benefits are being paid by current workers and not the money he contributed. How much he receives is based on how much he contributed and the number of years.
Most of the money workers pay today go to current beneficiaries, only the surplus is used to purchase treasuries that are used for the deficit. As benefits exceed contributions the IOUs are redeemed to cover the shortfall.
