I disagree with that being an intrinsic quality shared genetically by all of humanity, burned into our DNA. Rather, our ideas are shaped by material conditions, and thus different aspects are expressed more and less in different systems, ergo selfishness is not an iron-clad law.

Further, my point is more about asking why Communism can’t work because people are selfish. To me, that’s a telltale sign of not engaging with Marxist theory or how AES states are run.
