Communism Cannot be Achieved

why would you title the post like this, it reads like bait, especially with an 18 day old hexbear account, random meme pic attached, and your actual question in the comments

It is bait. I was just looking for opinions and insight. It was in jest, but I understand if people are irritated by it.
- bait as in you're just trying to piss us off and aren't actually here in good faith to find out our opinions. Like actively trying to get banned.

I thought this was a troll post

I have a limited understanding of theory, so take that into consideration. I have recently been researching geopolitics and world systems theory and trying to apply it to political economies. From my understanding, communism is achievable in simple societies, but difficult in complex societies. Complex societies tend to foster social hierarchies and authoritarianism due to their complexity. If anyone can give me their opinions I would appreciate it. Whether it’s an area for further study or someone else’s research.

I would just add on that authoritarianism is literally a meaningless term, in that every state is authoritarian. What matters is who holds the authority to do what. Read On Authority by Engels too, it's super short and dunks on "tankie ebil authoritarianism" quite easily
- Sure. I meant authority in its broadest sense. I was hoping for more of a social psychology dynamic. But, as is being pointed out, others have been down this path before. If the answers lie in economic theory, that is where I’ll start.
Have you had a chance to read State and Revolution yet? Lenin was really helpful to me.
This is my (very) quick and possibly poor understanding. Please read State Rev to see if I misrepresent it!
"the state" is a machine for class oppression. At the current time, the bourgeoisie use that machine to oppress the proletariat, at one point kings used "the state" to oppress the nascent bourgeois class and peasants.
the machine of the state is the tools for oppression. The "special bodies of armed men" are necessary for the oppression.
the proletariat can take the tools away from the bourgeois, and create their own tools.
the proletariat can use their tools to "oppress". the bourgeoisie into being equal with them (and protect the revolution in the process).
once class distinctions have been oppressed into non-existence, the contradiction of class will be gone, and the people's police won't have anything to do.
after long enough without anything to do (100 years? Who knows?) the people's "state" (i.e. "special bodies of armed men") will "wither away". The people's police will go make steel or something useful.
The important things here are that we can't predict the future, and that it'd probably take the whole world being socialist before a transition into communism.
And that the state being gone doesn't necessarily preclude centralized administration - it's not oppression to coordinate trains and garbage pickup or whatever.
Tldr - read Lenin not me.

- Damnit. I knew State and Revolution might have the answer, but haven’t read it. Does it stand alone, or should I read anything else before it?
  Edit: Do you use an e-reader? Kindle? Recommendations?
