I disagree. The tendency towards self justification is a universal human trait. Even if some may overcome that tendency, it is still qualifies as “human nature”.

This is germane because while labor and capital may perceive each other as the “enemy” and may in fact act counter to each other’s interests, nearly everyone perceives their own actions as justified.

To the extent that there is “social programming” involved which could conceivably change (unlike “human nature”), it has to do with the acts themselves, not the strong impulse to believe that your own acts are justified.
