 Pogge’s analysis is powerful, and includes a number of valuable positive suggestions about how we might begin to rectify these defects—including revisions in how pharmaceutical research is incentivized, and mechanisms for a global tax on resource use (Pogge 1994 and 2011). For the moment, though, we may examine only the major critical responses to which Pogge’s argument has been subjected. Most of Pogge’s critics agree with his contention that international poverty is unjust, in addition to being a violation of humanitarian duties. These critics, though, have frequently questioned whether or not Pogge has made his case that this poverty is causally ascribable to the international institutional set—and that simple revisions in this set could dramatically decrease global poverty.
