Think about this - the global rulers (of all industries) don't send their kids to public schools. They grow up with access to exclusive libraries of information spanning centuries and centuries of all the knowledge they've passed down through generations that explains how to enslave and exploit the masses. They send their children to exclusive private seminars on how to rise to the top of power. They keep this information only for themselves, and they spend their first 20 years in life being educated on how to become rulers rather than learning about gender studies and other time wasting public education curriculum. Surely a lot of this knowledge and information is psychology. Generations and generations which has honed it into a fine weaponized skill against the people. They keep these books and studies locked up away from the public and marry only into other elite circles, and keep the power structure going.
