Every communist country had been corrupted by capitalist countries who are scared of what communism would do to their money based system. Capitalism is a pyramid scheme, a ruling elite puts people in their place, communism doesn't have that elite. It doesn't need it. Thats why corperations and governments employ economic hitmen, they sabotage and destroy a country from within. Communism doesn't fail because its communism, it fails because people make it fail

but all those things are what the primal fight for survival has translated to in the modern world. if we don't fight for money we'll starve. we fight to be attractive to find partners still. we still act the same way we did thousands of years ago. it may be cruel, but capitalism allows for that life. communism would be great, but every communist country to date has fallen into corruption, poverty, and injustice eg the Soviet Union under Stalin. China under Mau (and even modern China)
