Well this predates Prescott Bush, you realize that? For this particular leg of the journey, you want to begin with Cecil Rhodes and his coterie of chums, Look at Carroll Quigley's books. The Anglo American Establishment, Tragedy & Hope. Contextualize what was happening post Civil War in America. Lots of bogus banking panics. Steady control of the money by the Robber Barons. The creation of monopolies, Standard Oil and the Rockefellers who created trusts, holding companies and all manner of organizational structures that are designed to obfuscate ownership. Then look at Jekyll Island, JP Morgan, and the European central bank model. Bankers, man, they had already got it all rolling long before Prescott started operating.
