 Although appeals to basic needs make sense intuitively, it is not clear that meeting basic needs is necessary or sufficient for an exchange to be fair. Two very poor persons who engage in an exchange are not necessarily exploiting each other even if they are incapable of meeting the other’s basic needs. Transactions can be fair despite basic needs being unmet. Conversely, two rich persons can still engage in a transaction in which the social surplus is unfairly distributed between them. \(A\) could buy \(B\)’s yacht for an unfairly low price. Such cases are certainly of less moral concern than unfair and exploitative exchanges between, say, a rich and a poor person, but this does not entail that the terms of the exchange are fair. Transactions can be unfair despite basic needs being met.
