What do you mean by that? I think it's pretty evident by analyzing AES states that shifting the economy into a more collectivized and planned direction comes with numerous benefits. What do you mean when you say it "doesn't work in practice?"
The Cuban people are doing better now under Socialism than they were under the fascist slaver Batista. Their life expectancies grew dramatically, literacy rates among the best in the world from widespread illiteracy, and they have one of the world's most progressive family codes despite massive embargo.
Ukraine is Capitalist, the fall of the Soviet Union resulted in 7 million excess deaths over the entire former USSR and obliterated what was once a stable economy. There were issues with the later Soviet Economy due to poor economic reforms, but other Socialist countries have learned from this, and these problems were correctable without nuking the economy.
Personal property is fine in Communism, the entire reason Communists want to collectivize industry and production is so that it can be done along a common plan to satisfy use, not for profit and hoarding wealth. Communists don't want to take your toothbrush.
I believe this is a classic tankie community. You won't be able to reason with these morons. Communism has never worked and it's a shit idea. There are other, better democratic socialist systems. Communism results in everyone being poor except the fucking dictator running that shit show.
That said, communism might still be better than the shitshow the USA has to go through.
I think trying to force communism is bad. Communism in my mind is inevitable, but we’re no there yet. Only when human labor is worthless and capitalism crumbles under its own weight will communism finally be viable and good.
