Some of the most significant insights of effective altruism in terms of finding more effective ways to help others have come from highlighting different beneficiary groups.
This makes me want to split off “people in extreme poverty” into a distinct group of beneficiaries—I suspect that for many the “aha!” moment in their EA journey was realizing that these people exist and can be helped. Also, it seems to me that the interventions available for helping people in extreme poverty are quite different from interventions that help richer people; AMF won’t help richer people much, and direct cash transfers help richer people less. However, this would complicate the three-way split that you highlight here.
