Justice as mutual advantage appears to show inadequate concern for those that are insufficiently useful to others, implying that those that are most in need of the protections of justice fall outside the scope of justice as mutual advantage. Vanderschraaf offers a novel reply to this objection. He presents a game–the Indefinitely Repeated Provider-Recipient Game–which establishes that in some situations justice as mutual advantage can show concern for the vulnerable. This finding, however, does not match the problem raised by the (...) vulnerability objection, for the objection says that in all relevant situations, justice requires equal basic concern for all–vulnerable and non-vulnerable alike.
