My “honest question” was not asking if a better system could be described, that much is obvious. My question was about the intent of statements like OP. I was probing at the idea that current socialist or communist examples are better than capitalism (perhaps marginally). My understanding is that doesn’t seem so.

Per my other reply, I think the answer to my question is yes, the path forward is to trash all the systems we have at the moment and shoot for something closer to what you described.

Read the phrasing of my question, I asked if any systems exist, not theorized.
