watch the video on the rules for rulers by the youtube channel cgpgrey for one explanation.

One thing I'll add that I haven't seen mentioned is communisms relative weakness in the propaganda department. If you look at democracy as a bunch of competing interest groups i.e. parties trying to win the masses over to there side to win, then there main tool / weapon is information that will make the opposition look bad and your side look good, i.e. propaganda. Good propaganda requires intimate knowledge of people's desires and a knowledge of how to shape those desires to the benefit of your program. Capitalism is very good at this due to competition forcing them to better understand there customer so they can sell them more. Capitalism creates great salesman which is fundamentally what you need to create good propaganda. You can see this expertise most plainly in advertising pushing the message that consumption is good, fulfilling and will make you happy.

This expertise combined with the large amount of resources capital can Marshall to push there message makes electoral politics extremely difficult for communism or any program that goes against consumption like environmentalism. Even if you completely eliminate capital and it's control over media in one nation foreign actors will still come in using the same expertise and resources to try and bring back capitalism. So since communists can't compete electorally with a free press they go towards autocracy to keep power.

OP how much of today's markets and politics are definited by Oligarchs and the rich? Can you really say that a plutocracy isn't it's own kind of dictatorship?

Even more so, many westerners have been fooled by culture to think this is natural, inevitable, and good.

In terms of per capita rates, the Irish Catholic Church was incarcerating more of Irelands population than Stalin did to Russia during his reign.

Just two companies; The British East India company and the Belgian Rubber plantations of the Congo killed more people than Stalin or Mao (especially if you factor out the deaths from Lysenkoism, which wasn't a part of communism).

So early Capitalism and Colonialism killed far more than Communist dictatorships have....

And finally there is this to say - Communism is an economic system designed to interrupt plutocratic rule. It's not a governmental system of elections and checls and balances....

...and if we are to be the most up to date with this: China and Vietnam have Socialist Oriented Market Economies. The one in Vietnam, has almost eliminated homelessness entirely. Is that a dictatorship compared to the woes of the west's housing crisises?

Early systems from both economic models - Capitalism/Colonialism and Communism - both had events of mass killings. Both have seen dictatorships... You only focus on these things in the Communist model, because of your background. Likewise, someone from China pr North Korea might hear more about the famines, deaths and genocides of the Capitalist and Colonial corporations I've mentioned above.

P.S. Are Cancer deaths from chemicals Capitalists kept on the "safe" list indicative of a dictatorship by the wealthy? What about the deaths and famines from weather disturbances in the climate? If we're counting the famines under Communism, then why not these things to? It's because of a hidden Western ideology/indoctrination culture.

What hierarchical structure exists in any type of system that doesn't breed corruption?

"Power corrupts. Absolute power corrupts absolutely."

Many informed responses already so I'll add my uninformed opinion.

Political change has never occurred in a vacuum. Communism is a direct threat to capitalism. So ~~the US~~ capitalists will do everything in their power to undermine and disrupt communism.

Because, at a high level, communism requires that a leader or group of leaders get things on track and then give up all of their power over time. Instead, the type of people who tend to lead revolutions are the same type of people who are unlikely to want to give up power and instead end up wanting more power. So no true communism has ever existed because it never gets to that phase.

Well it didn't happen in every case. In the UK socialists became a big faction within the post war labour party and created the NHS. Almost every other country in Europe has a similar story with the creation of their own healthcare systems. Russia and China have never been democracies at any point in their history so maybe that has more to do with it than socialist and communist ideas.

Greed. The Achilles heel of humans since the beginning of time. Greed breeds hate, hate breeds fear, and fear breeds violence.

Because it is a dictatorship.

A dictatorship of the proletariat.

For real though we've not seen communism yet.

So to begin with all communism so far has never been democratically voted in as far as I know and pretty much starts with an ideological military government that then needs to transition back to democracy.

Many do transition to a one party system where all democracy is contained within the party and essentially becomes a "primaries only" type.

Then slowly over time power consolidations and purges bring it towards a dictatorship because there are no checks and balances against it.

So it seems to me that the only way to get to the ideological communism is through democracy and constitutional changes, proportional representation and coalition governments that don't allow any one toxic pernon to consolidate power.

The vanguard party is essentially an oligarchy. It chooses its own successors, and we’re supposed to trust that they are too smart and on the lookout for the populace to not abuse power selfishly. A core tenet of anarchism is that while people may hold authority, nobody should hold positions of power.

Though I would say that while quite corrupt, one-party, and authoritarian, Cuba is a lot more democratic than people think

Because some people are more equal than others

Realistically anybody who can take control of a country is a bit of a ruthless cunt, and ones that take over in an armed uprising especially so.

It's not a massive shock that some of them don't want to give up the crown once they've got it.

Even in so called democracies, we basically get to choose our "king" from a heavily vetted list. It ain't going to be people like me and you rising to the top.
