Why does the West say that socialism is the product of the 2th century?

Because the first country established by ideals in the 2th century was founded. The theory of socialism was put into practice for the first time.

At the same time, at the end of the 2th century, because the United States and the Soviet Union were in a weak position and were about to fall, China, as another high-profile socialist country, would probably follow in the footsteps of the Soviet Union and disappear in the long river of history without the implementation of such policies as reform and opening up. In this way, the end of the two countries will become strong evidence that western countries advocate that the capitalist system is a perfect system. Socialism will become the legacy of the 2th century and a joke in capitalist propaganda.
