 To be convincing the argument must show: firstly, that severe global poverty requires immediate action; secondly, that it is a matter of justice, not charity. To that effect, it is crucial to show that the extreme poverty of some countries is not simply the result of endogenous factors (e.g. bad governance; corrupt political culture, etc.), but is linked to a global political and economic order that systematically produces an unjust distribution of resources and political power, which rich northern countries, as its main beneficiaries, are in no hurry to  reform.[20]  The third step in this schema purportedly shows that justifications of restrictive immigration policies premised on ethico-political claims lose much of their force in the context of profound international inequalities and injustice. Proponents claim that regulating immigration in order to preserve the integrity of the political community is a legitimate goal only if duties of international distributive justice are satisfied (Tan 2004, 126, referring to Tamir 1992, 161). The argument’s upshot is that “[r]ich Northern states have a double moral obligation to seriously fight global poverty and to let more people in” (Bader 1997, 31).
