Well yeah, I'm just wondering how Cockshott came to define "to each according to his need" solely as the provision of special aid to those that need it alongside a labour-credit economy.
Alright leftypol...
Revisionism because he's afraid of utopianism that statement brings with it.
he's an idpol troll.
I think the idea you are looking for is called historical materialism. You can find a really nice explanation in chapter 3 of socialism: utopian and scientific by engels. There is also a video by the yt channel communist current that helps make it digestible.
Communist discourse is overwhelmingly materialist. Which might mean you might not get answers based in terms of something as ethereal as "natural rights" again see the first paragraph of ch.3 utopian and scientific.
"The materialist conception of history starts from the proposition that the production of the means to support human life and, next to production, the exchange of things produced, is the basis of all social structure; that in every society that has appeared in history, the manner in which wealth is distributed and society divided into classes or orders is dependent upon what is produced, how it is produced, and how the products are exchanged. From this point of view, the final causes of all social changes and political revolutions are to be sought, not in men's brains, not in men's better insights into eternal truth and justice, but in changes in the modes of production and exchange."
