"Marxism has never existed outside of mental exercise. Every single time it has been imposed it has failed to do anything but act as a rhetoric for power and control."

This, as the last commenter said, is completely ahistorical and incorrect. Every society in which Marxists have come to power was previously unequal, impoverished, unindustrialized, and most of the time a colony of another power. Every time this has happened the countries end up industrializing and eliminating severe poverty within a few decades, as well as providing housing, healthcare, food, transportation, work, and every other basic necessity for each one of their citizens. This can be seen with a simple look past the cold war rhetoric and into the actual history of the world.

Communism was also the primary force which defeated fascism everywhere that it popped up up until the 80s or 90s.
