This is what I am interested in hearing other people answer first. All I can say is that it is difficult for socialism to succeed in a capitalist dominated world. While I am also curious about the argument regarding class struggle, I believe each country's path to socialism will be different in different nations. China at this time is serving a massive role in maintaining peace as much as possible and to prevent another capitalist takeover of their country. This is necessary, especially with their 100 year plan and goal toward US dedollarization via becoming a world leading centralized nation mutually benefitting in trade with Eurasia and Africa. While people were hurt in the process, I believe the emancipation of the proletariat has an improved chance of succeeding across the world than if China had the same fate as the Soviet Union.

I suspect most people would have wanted the Cultural Revolution to succeed if it would have yielded better results, but that is not what happened. What is important is understanding the material reality and how it was impacted by Dengist policies, which brought China to its current stage today. Perhaps in the future we can see other countries have revolutions and manage to stick to the socialist only road, though I believe it is likely the case that China essentially took one for the team and allowed other countries to not have to go through the same struggles and risks.
