 The first answer is offered by the unequal exchange account, according to which A exploits B if and only if in their exchange A gets more than B does. This account effectively collapses the normative sense of exploitation into the technical one. But critics have argued that this account fails to provide sufficient conditions for exploitation in the normative sense. Not every unequal exchange is wrongful: it would not be wrong to transfer resources from workers to people who (perhaps through no choice or fault of their own) are unable to work.
