I know the book exists as I'm very familiar with the kinds of claims that get repeated in threads like this.
To me - these claims seem to fuel a conspiracy like mind set about why certain efforts or movements fail. "Because the billionares didn't want it to". "Or they bought the media and control the narrative". "Its all just a uniparty!".
If I were to replace the word billionare with the name of the first Abrahamic religion, you and I would both see that view point as low intellect nonsense. And it would be. But somehow, sub in the word billionare and then it becomes brilliant analysis for some.
