Just because something hasn’t happened yet doesn’t mean it is guaranteed to happen in the future.
I didn’t think that I needed to explain that to you. I was wrong. Sorry.
I am not saying things can’t happen if they haven’t happened yet.
I am saying if Socialism and Communism have existed for centuries and that whole time they have had disparity. What reason is there to believe that disparity cannot exist in socialist or communist economies?
I didn't move the goalpost, Communism as a concept is a Stateless, Classless, Moneyless society that can be achieved after Socialism has built the groundwork for it. It hasn't been achieved yet, because there have been no developed Socialist states yet, and Communism is a global, international system. It takes a long time to get there, it isn't just something that poofs into existence.
It's a Stateless, Classless, moneyless society. It's hard to build, but it's possible to build towards, and will take time and development to get there.
