Capitalists need workers to oppress. Without them, they would have nothing to give them a feeling of superiority. Mincing people into fertilizer would surely be a fun pastime for the rich, but it's hardly a sustainable hobby
You have a rather one dimensional moustache twirling view of the world. Let me guess, communism is the one stop solves all problems in the world solution without any negative side effects?
You do understand that that is not how the world works, or for that matter, how anything works?
Seriously, your comment is plain nonsense. Yes, captialism has a shitload of issues. Yes, there are rich and abusive people out there. Yes, communism is responsible for countless millions of deaths and tortured...
Instead of making up weird fantasies, how about to try to come up with an idea that would actually make things better?
Communism as Marx described, has to do more with the complete automatization of the means of production, and the subsequently change of the structure of society, as a result of post scarcity.
Remember that just past Mars humanity has a near infinite repository of resources, it's only on this earth that we are subjected to the rat race, when we have the wealth of the universe so close.
You may think that I'm dreaming, but if we let capital unchecked, it will destroy us, and destroy earth. We have nothing to lose but our chains.
I am all in favor for heavily regulated and checked capitalism. Like it or not, its the most successful system and it can be a source for good when heavily regulated and used as an input source for a socialist system that takes care of all.
Thinking about how to make the world better starts with fantasizing, and moves on to theorizing and debating ideas. Calling the many decades of socialist and communist thought just fantasies goes beyond all reason. At this point you're just ragebaiting. This is not how you talk to people.
