I posted this video before and thought it was worth another look. This is a video originally done by the Free Congress Foundation during the 1990’s. The film examines a little known but highly influential Marxist group known as the Institute for Social Research (aka Frankfurt School) that gathered in Frankfurt, Germany in the 1930’s to give new life to communist thought when most of the predictions made by orthodox Marxists of how international communism would be achieved did not come true.
How Marxism is taught in most colleges and universities is due to the efforts of the Frankfurt School. One of the ideas floated by them helped spurn such Leftist causes such as anti-Vietnam organizations and the environmentalist movement. Ex-Marxist David Horowitz is also interviewed.
