It is probably much too simple for you to understand so i will attempt to educate you on the frailities of human nature.
When the masses become tired of exploitation they tend to revolt and band together.
Once the objective is achieved they again go back to sleep believing the war is won and it can never happen again.
This is the lesson it happens over and over again throughout recorded history.
The power mad humans never go away, the thugs never go away, the exploiters never go away, the connivers never go away and for all you non-believers out there the seven deadly sins never go away.
This is what some call human nature and others call human stupidity.
