But for them, this level of control is not enough. Do you believe they are sane people, who have things like satiation and moderation?
Control is never enough, and those sick for it don“t stop until they destroy themselves in the process. If it“s possible to control completely a slave, they can“t stop in just indirect control trough propaganda, the only acceptable end is with total physical control like we control an animal in a lab cage.
Think of the rich people who gets 100 Billion in their account. How many of them are you seeing satisfied with they achieved? The more you have, the more you want to have much more. There is only one thing that stop a psychopath seeking power over its prey. Death.
