Even just as a technicality, the 1% have not always existed, most tribal societies did not have class divisions like that. Both anthropological studies of existing tribal societies show examples of that, and the archaeological record, too, lays out it was common.

And I understand feeling like that, but it is a pretty weak argument, tbh. It is even hard to engage with, because it’s basically starting at a completely different outset of concepts and understanding. Firstly, it reduces socialism to only systems of perfect equality of power - when even Marx acknowledged that this is not only impossible but also undesirable.

Then it just packs all kinds of class arrangements into “The 1%” and “the worker class”. Was European feudalism like that? Ancient palace economies? Tribal gift economies? Pre-historic tribal arrangements? The Incan/Andean planned economy? Each with their own complexities, class relations and all showing that the basic idea - humanity evolving along it’s material capabilities and necessities - hold true.

Lastly, related to the idea that proper socialism would mean perfect equality of power - sure, corruption in some way has probably always existed. People will also always murder each other in some way. Using that as an argument to say it is impossible to establish a system that minimises murders is how your reasoning sounds to me.

And the system is always what limits or enables the way this corruption and gaming the system plays out. How much property and/or power can be concentrated? Capitalism concentrates vastly more wealth and capital than the systems before it, both for good (e.g. the development of productive forces has enabled many things) and ill. Just because perfection may not be possible, does not mean a system without exchange of value and capital accumulation is impossible (has existed before for sure, yes, even for more complex economies than a small tribe), and it does not mean it has to exist in a way that is more barbarous than the current state of affairs.
