In recent years, the flow of undocumented labor from the global South to richer nations has increased considerably. Many undocumented women workers find employment as caregivers for the dependent elderly, whose numbers are burgeoning in affluent countries. Here we present a profile of undocumented non-citizen caregivers in the United States and delineate some of the key injustices they suffer. After identifying the causal factors responsible for the flow of undocumented labor from the global South to richer nations like the United (...) States, we discuss the criteria that a theory of transnational justice must meet if it is to address the problem of justice for this population. We argue that Iris Young's "social connection" model of responsibility is a promising approach for helping to correct the injustices suffered by undocumented, non-citizen caregivers. (shrink)
