What happens to the working class after they take control? History says they don't stay the working class. They become the new rich or the new military leaders. They do their dance just to fall back into the same shit patterns they worked to overthrow. Their revolutions mean nothing because they just use violence as a response to violence rather than taking a holistic proactive approach to the advancement of mankind.
There is no such thing as genuine democracy; each individual must be taught how to control themselves, take responsibility for their actions, and move beyond the ways that failed us so many times. A tyranny by majority vote is still tyranny.
