Every human starts as a baby with clear mind
At any point of history, there is some or another opportunity for human-by-human exploitation along with a great spectrum of handy instruments like brain washing, extortion, slander, etc., and this kind of innovation will never stop until we manage declaring the freedom from human-by-human exploitation as the very first and fundamental Universal Human Right. Every human starts as a baby with clear mind. Therefore, we cannot avoid education. But we can stop brain washing by declaring any activities resulting in human-by-human exploitation illegal and futile.
