China is successful from the capitalistic point of view, but it failed to uphold the ideals and principles of the system described in the document. The exploitation of the people is through the roof.

Edit:

To further explain my point: Communism is a flawed system that cannot exist in its idealistic form due to the excessive concentration of power in the state, leading to three potential outcomes:

1. The collapse of the country.
2. The transformation into a state capitalist system, as seen in China.
3. The transformation into an authoritarian regime, as seen in North Korea.

Communism is, in my opinion, a pipe dream because it proposes a classless, stateless society where the means of production are collectively owned and wealth is distributed equally among all members. However, in practice, historical attempts at implementing communism have faced challenges in terms of human nature, central planning inefficiencies, and lack of incentives, leading to economic stagnation, authoritarian rule, and often the collapse of the system.
