Communists didn't learn the lesson after racking up well over 100 million deaths.
You can't fix stupid, they lack the capacity to learn from mistakes.
It's not so much stupidity as greed and a lust for power and a lack of compassion for their fellow man. The pieces of pushing for communism want to be at the top of the food chain gaining all of the wealth of this great nation and they have no problem with the little people under them suffering and dying for their position in life.
