[Terr_]

While I am normally in team "hey scale it by capita", this case makes me hesitate. (Would we also need to factor in statewide cost-of-living values?)

If $X is exported from residents of my state out to support another state, that's the same local impact regardless of how populous the destination is or how finely that $X gets split after it arrives.

In any case, I think it's enough to support the idea that there's a tension (if not contradiction) where the states that receive the most absolute benefit are also the ones electing politicians who pretend the exact opposite.
