I should have mentioned that the first video above with Prof. Randall Wray of the University of Missouri-Kansas City, is from a series at Columbia University, New York. Nothing prof. Wray says is controversial to economists, though politicians contradict it.

It is part of a larger video, with questions from audience. Also, another speaker about money and accounts in ancient history, Sumeria, Babylon, etc.
