My big issue with socialism is more about the implementation. I’m not sure there is a way of enforcing socialism that isn’t antithetical to the goal of socialism- a more even distribution of power (which we quantify as wealth in a capitalist society).
In general, I don’t think there are any stable economic systems that don’t decay into feudalism when abused. At least for the economic systems we’ve come up with so far. The best one I know of is the gift economy, but that requires people to not expect something in return, because otherwise it could be reduced down to capitalism.
In short, all the economic systems so far, despite their best intentions, reinforce inequality.
