The News Hour has outdone itself with a fascinating interview, punctuated by a rap video. Primary subject of the interview is Lord Robert Skidelsky of the University of Warwick, a biographer of John Maynard Keynes. Also interviewed is stimulus skeptic Russ Roberts of George Mason University. Off and on we hear a very clever rap song about Keynesian economics. The segment really gets to the heart of Keynes and his critics.
