The first form of control is the conditioning process, which is subtle to some degree. We are conditioned by culture, and upbringing. This path is passed on by those that bring us up from birth, which is also subject to this conditioning. This condition is the result of sociological and psychological interventions, such as fashions, acceptable behaviour, ethics based upon the conditioning that you have learnt.
There is also political conditioning whose use of language, media, and body language is a powerful influence, and affects all other forms of conditioning, and these results in ones belief in nationalist divides and the use of images created by our selves, such as flags, and other symbols like statues, medals, and emblems, all of which are created for control and a sense of belonging which enables the majority to be controlled by the minority.
Economics is another very powerful controlling device, and almost all peoples of the Earth are tied into this system. It is an artificial system which incorporates the belief of value of things, i.e. one thing being more important than the other, based upon the sociological conditioning processes and other processing being involved to reinforce this belief. This enables control to be wide spread, we are almost forced into this system for the basic needs of survival, and it also reinforces other conditioning processes, as those mentioned here.
It's all down to the creation of hierarchical conditioning. Where people are either lead or force to believe that a few people are better and more valuable and important than others. This false assumption and perception has then lead to many fake and corrupt pixie systems that enable a few to exploit and control the lives and potentials of others. Everywhere in the human domain is hierarchical at home, at work, in politics, governance, socially and all re-enforced by hierarchical religion, social, political and so forth.
All serve the same imbalanced agenda... To judge, place, control and exploit people into some form of willing or unwilling submission. So as long as people are willing to bow down to someone else. There will always be the huge disparities the hierarchies’ produce; they are the 1% who takes ownership of everything possible.
Of course all of the above is a house of cards, and those that can see the conditioning process at work and hopefully influence others to see these deceptions used to a large degree by those that wish to manipulate, lie, deceive, and control our lives, and prevent the truth coming forward, which encompass a greater understand of who we are, what we are, and the purpose of our existence.
