How would that system work and how would it account for minorities? Should people be allowed to do as they see fit even if the majority determines it to be a waste of time or resources? The second you start getting into areas of central planning is when the oppression starts. If your proposed system is more smaller communities, that is when the famine starts.

I know it seems old to say that this has all been tried before but it really has. The USSR started as a unity of small communities (soviets) and they found that they could not run a society that way so they centralized planning. Racism played a part with the Holodomor, literally taking food from the most fertile region in the USSR and ensuring that Russians had enough. Anyone who was not Russian was worse off under the USSR which is why you see the eastern European former Soviet block countries be so anti-communist and so anti-Russia. It is also why you see the Russians remembering it fondly. They were the benefactors as the majority in the system. They also left the USSR rather than be in a majority Muslim USSR as Eastern European countries split off.

So, that's all fine and well you might say but that's not true Marxism because they centralized planning. The Chinese agreed with you which is why they refused to centralize for decades causing huge famines. They too eventually centralized planning. They too have used this economic power to oppress minorities.

You can argue that Marxism is more of an ideal that you are striving towards (and Marx himself did argue that) and that is the current CCP argument. They have a mixed economy like any other but they do not allow any party other than themselves which provides no check on power at all. It begrudgingly allows businesses but has no checks on their power until it endangers the efforts of the state. As long as the state, people, and businesses align in efforts, they are more efficient...and we're unironically at the definition of National Socialism.

I think these conversations died a long time ago so people forgot how to have them and relate to them in a way that they can understand. I also think that way too many people view socialism as a catchall for forcing through the changes they would rather see in society instead of doing the groundwork to actually change society. Giving more economic power to the majority won't make it less racist, you just gave the racists more power.
