Everybody knows (who is free) an educational-experimental film that uses the 1980 PBS series Free to Choose, economist Milton Friedman’s consequential argument for “free markets,” to trace a history of the changes in the political economy from that time to now. The film is also about who the audience for my film might be, about what “we know” and why “we” believe what we do. I am using the immediate appeal of Friedman’s arguments to some people and rejection by others to explore this.
