Communism is an aspiration, an aspiration is an ideal, a dream, a longing of something that would be perfect, but hard to build because it has to clash with human nature and against the egotism of humans and the egotism of the elites which usually try to guarantee their own interests above those of their nations and of their own people. But they are the ones that prevail because they have the economic power, the political power and the military power.
