 Taking these points on board, even some of those who have endorsed the principle of reciprocity and the basic idea of work-conditionality have also cautioned against applying work-conditionality in a way that is insensitive to the background distribution of wealth and opportunity in society (see, for example, Gutmann and Thompson 1996: chapter 8; White 2003, 2005; see also Daniels 1981: 160–162). They argue that the principle of work-conditionality should be suspended, or at least moderated, if the background distribution of wealth and opportunity is not sufficiently just. Indeed, given the risks involved, and the complexity of creating the conditions for the fair enforcement of work obligations, there is a case for avoiding work-conditionality altogether even if one accepts the underlying principle of reciprocity (White 2017).
