still, what we're looking at there is: "selfishness" is a product of conditions. selfishness is built into whiteness, itself built into empire, itself built into capitalism. these things cannot be disentangled, but they are holistically *unnatural.*
there is a history of *specific* events and human actions that led to these conditions existing, and these conditions have only been in place for (depending on how you count and how fine-grained you are about "these conditions"), like, half a millenium, out of the forty-plus millenia that anatomically-modern humans have walked the earth.
"selfishness" does not rise organically out of "human nature"; it arises out of systems we made, and which we can unmake.
