Greer has written often how the Establishment in the various fields of Science have been co-opped by financial concerns of corporate money and grants. Industrial money buys results to say what advertising departments want, no matter what the research says. In addition, government regulators have been bought off with the revolving door of corporate lobbyist jobs. So instead of cheap no longer under patent medicinal cures being recommended, we must all take the latest questionable chemical vaccines that just coincidentally make pharmaceutical companies trillions.

One thing not mentioned as well, is the dogma of established scientific "Truth™". Reputations within the education, medical and scientific community are made or broken by the research papers which are allowed to be published. If you do research which contradicts the accepted beliefs, or do a study which casts doubt on the recommendations of famous people within science, the Powers which control what is told to the public will squash you like a bug.
