I've read The Communist Manifesto. There are indeed parts of it that are sensible in isolation. The problem is that taken as a whole, Marxism, Leninism, Maoism, etc. are deeply flawed ideologies doomed to catastrophic failure and devastating results. History has shown us this repeatedly.
To Quote Ronald Reagan...
“How do you tell a Communist? Well, it’s someone who reads Marx and Lenin. And how do you tell an anti-Communist? It’s someone who understands Marx and Lenin.”
What history has shown us is somewhat weaker than you say — for all the stuff they did badly, for all that they wildly missed their own raison d'être and became just another power structure for just another bunch of essentially aristocrats, it did also get Russia from the Tzars to orbit in 40 years.
But that aside, when you're already getting failed and the people failing you specifically hate one thing, it's very easy to reach for that thing.
To your quote: Well, I'm not a communist (unlike a previous partner)… but I'm also not a capitalist, because I see that capitalism also is a deeply flawed ideology doomed to catastrophic failure and devastating results, and that history has shown us this, too, repeatedly.
I'm also not "anti-" either of them, because I'd rather see someone take the best of both and find some new mechanism to deal with the other repeatedly observed historical fact: that a non-trivial fraction of the population are power-hungry sadistic arses. To quote, albeit from fiction: "To summarize: it is a well-known fact that those people who must want to rule people are, ipso facto, those least suited to do it. To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job." - https://www.goodreads.com/quotes/2416-the-major-problem-mdas...
(Both capitalism and communism have failure modes separate from the problem of dark triad personalities, but both sets are much easier to deal with if your society has also solved the problem of dark triad personalities, and a society does also need to solve the problem of dark triad personalities irregardless of what else it does).
It’s almost like… how can we take the nice social parts from communism - and mix them benefits of capitalism. Almost like, some sort of democratic socialism.
Good thing when people "support communism" they're not calling for a specific system like the Soviet Union, but just for a higher adoption rate of the good things that fall under the umbrella term.
How do you achieve this without creating a brutal authoritarian regime to seize the means of production and silence opposition? How do you allocate resources and labor fairly?
Marxism is a flawed ideology because it doesn’t account for human nature.
I recently started reading Henry Ford books and to me it looks like he has achieved the best of both worlds - at least until he passed away. One thing especially resonates with me - decreasing the prices without reducing the wages so that the profit gets close to zero, then find ways to make the manufacturing more efficient and less costly. While the new profit gradually grows - gradually increase the salaries. Then rinse and repeat. In the end people have good salary, can buy cheap (but still high quality) products and have joy while working.
I agree with you that Marxism is flawed, that as you say it doesn’t account for human nature.
But: There's no additional overhead to "seize the means of production" vs. any other system of governance and organisation, given that corporations, money, ownership, and the law are all things that any functioning system of government controls anyway, regardless of if they want these things to be collectively owned (/nationalised) or privately controlled.
Now, my former partner who is a self-identified Communist of some kind (I can't remember which kind), she wants to abolish money, and abolishing it rather than using it would need quite a lot of extra effort.
> How do you allocate resources and labor fairly?
I believe the general claim here is "democratically". This doesn't really work too well, but on the other hand, neither does letting people accumulate so much money they become the de-facto leadership with the carrots and sticks of "I will move my business to whoever has the lowest tax/cheapest labour/least expensive safety requirements".
Consider also that normal people are nowhere near as carful with language use as you or I may wish; some of the people you're worried about may be identifying themselves as "Communists" in the first place only because they're exactly one step to the left of the Democrat Party's Overton window while also repeatedly observing the US Republican party describe the Democrats as "socialists".
(Conversely, my former is one of the people I expect you to be correctly worried about, as she agreed with my assessment that she was to the left of the Cuban communist party).
