At what point do you decide that's an inevitable outcome, rather than an unfortunate unexpected outcome that happens every single time?
You never want all power to be in the hands of a single group of people, capitalist democracies separates private from public, so politicians regulating companies are not the same people who are owning those companies. Communism can never work since its an autocratic system with a single player, you need multiple actors.
And yes, in some capitalist democracies company leaders are close bedfellows with politicians, we call that corruption, it isn't like that in all countries.
Impossible. Communism has no concept of state (nor money, nor class). That's, like, its defining feature.
Of course, you can't just wish for class, state, and money to go away. They are necessary features of our current world. Communism is the imagined outcome of what happens after we achieve post-scarcity. It is a work of science fiction. Star Trek is a more modern adaptation on the same idea.
> Communism can never work since its an autocratic system
If it were more than science fiction, it is literally the opposite, but, again, depends on post-scarcity. You are likely confusing communism with the Communist Party, who believe in an autocratic system being necessary to pave the way to achieving post-scarcity, with, on paper, a desire to get there.
While the Communist Party does believe in socialism, that does not sum it up either. That would be like trying to tie the Republican Party up in a capitalism bow. They do believe in capitalism, but so does the Democratic Party. Yet they are clearly different parties with some very different ideas.
> or any existing embodiment of the first stages of Communism.
The USA is the country most in the first stages of communism. Its technical innovation has nearly pushed food into post-scarcity territory (some argue it is already there), and it is working hard, harder than any other country, to do the same in other areas of production.
While some of your points resonate with what Trump is doing, for the most part he is an aberration and there isn't yet much indication that he — or anyone in the future — will get away with it.
Ironically, it did become a dictatorship after the USA staged a military coup and overthrew said government, but anyway...
Communism doesn't exactly promise anything. It is a sci-fi imagining of what the world will look like in a post-scarcity world. Star Trek is a more modern adaptation on the same idea. Would you say Star Trek promises us something? Notably what communism does imagine, though, is that there is no state.
If you read back in the comments, you'll see we're not talking talking about communism at all, rather "communist state". As before, communism rejects the concept of having a state, so you know we cannot possibly be talking about communism. Instead, "communist state" usually refers to a country under rule by the Communist Party. As Chile was ruled by a Marxist inside a Communist Party coalition we said that was likely close enough for what the earlier commenter was trying to convey.
Chile was a technocratic democracy then. Is that paradise? That is in the eye of the beholder, I suppose, but it must have been pretty good else why would the USA have wanted it to dismantle it so badly, undoing what was, at the time, one of the most stable democracies around?
