I don't think we need more research. We just need to look around and accept that we have a system built on the competitive devaluation of humans to their places and each other, as well as the popularity of Spectacle As Final Merit.
Competition paints the targets. Resentment pulls the trigger.
"In a society based on competition, you inevitably get fewer and fewer winners and more and more losers." -Wendell Berry
Competitive losing is no way to run a society.
Capitalism/colonialism has put everyone in an arena, then dumped trainloads of weapons in the mix and turned on the TV cameras financed by the advertising/education that decides what is newstainment.
Varying levels of bullying and resentment are fed and watered with sugar, drugs and sex until all of the animals are foaming at the mouth (the system's most profitable state).
They are always coming up with new weapons, new drugs, new clothes, new toys, new advertisements, new cars, new excuses for the powered to be corrupt, then looking for 'reasons' that the proles are shooting each other on TV.
"Reason's got nuthin' to do with it." -Mr Gibbs, Pirates of the Caribbean
