IMO, the funny thing is the United states (1950 - 1980) is probably the closest example of the Marxist ideal you can find. After industrialization you had violent conflict between workers and factory owners that resulted in places like GM being gutted by their workers who kept the fruits of their labors. Arguably by the end of the cold war it was more a question of how you organize a communist country than would you create one.

PS: Of course with automation and computing many of the old assumptions stopped applying but it’s hard to complain when someone only sees 75 - 100 and not 150 years into the future.
