It's always weird to me that people associate Dictatorial Command Economies with Communism. On one hand they like to label themselves as communist but on the other hand y'all really gotta learn to read between the lines. It's like saying socialism has failed buecase the Nazi's had socialism in their name.
This is just the No True Scotsman argument. Every communist nation has always insisted that the dictatorship is a necessary transitional state so that true communism could be achieved, and been run by parties espousing the need to achieve that communism. Those dictatorships have never truly moved towards that.
Either communism is impossible or communism is dictatorship. You can pick either one, but there's not another option.
3 examoles i could give for socialism two of them where crushed by the Soviet Union. Revolutionary Spain and the free territory of Ukraine. One which works since 10 years (while trying not to get crushed by Turkey and IS) and there are some more such free territories which therefore also democratized thier economics.
Also fuck tankies btw
Communism is to a co-op what socialism is to a guild of freelancers.
Socialism has the government control the main industrial output but you're free to do and own your own stuff outside of that. Ideally the government controlled sector's profits would be used to benefit the people again (free healthcare, etc)
Oddly the CCP (Chinese Communist Party) is the best modern example of socialism.
Out of all the times communism has been attempted, please point me to an example of a stable communist nation which promotes freedom for the working class.
Communism aims to establish a classless (no rich or poor), stateless (no military, police or any other tool of class oppression), and moneyless (no currency of any type). No country has ever achieved that. Therefore, communism has never been attempted, let alone implemented.
