I think it must have been in the late 1970s/80s that I watched this first on filmstrip.
A disturbing wake-up for the uninitiated fools:
The Capitalist Conspiracy
An Inside View of International Banking
Written and narrated by G. Edward Griffin
This is a video adaption of a documentary filmstrip tracing the history of a small group of people who control the money systems of the world. It shows how this monopoly is protected by governments and how the group's vast wealth is derived from creating money out of nothing. We see how this group wields power through government, foundations, education, and the mass media.
