I don't think the ideology of communism is the issue, on paper it's a very sound ideal.
The problem is when greed/other human attributes gets involved it stops working. As with any of them, it's all about the people and how they implement it. I don't think capitalism sounds good at all on paper, but has worked for quite a while, mostly due to some degree of working standards and unions.
Remember most of these haven't been in use for longer than like 100 years. Before 1920 it was largely a mix of other religious/monarchy ideals.
Right, but isn't the ignorance of actual human character shortcomings a huge reason why communism can't ever work, even on paper?
People are inherently self-interested. I would argue that any proposal for an economic system or government needs to acknowledge this at the outset and be built based on that foundational belief.
