Here’s a little thought experiment I came up with: let’s say the population of a large city under a communist government was suddenly transported back to prehistoric times. None of their technology came with them, only the knowledge in their brains. Let’s assume they survive, would they be able to keep living under some sort of Marxist-leninist/communist ideology? In the complete absence of technology, do you think a large scale communist society can be maintained, or would it necessarily have to dissolve into something more akin to “tribal communism”? Would the tribes they revert into start warring with each other for resources like actual prehistoric tribes did? Do you think the people in this situation would be able to hold on to communist ideals from a mental perspective, or would people start wanting a capitalist or other system?
if you arrive at a communal society, and don’t taught them about private property, but taught them about technology, they will improve quality of life, but not change their economic system. so, the question is about what is needed to maintain the tribal communism while increasing the productive forces. building elective councils to manage the social life, instead of putting the power on priests or military leaders is a good star on my opinion. as the productive forces increase, we need to manage large stocks of food, raw materials and coordinate labour division. if one person or a small group of lifelong leaders do this, we have the gradual privatisation of the communal goods.
