This week we look back on what happened in Iowa and ask whether the Sanders campaign can really be compared to Corbynmania, with a little help from our friends in the Brooklyn Nailbar. And what is a populist anyway? Our special guest is the economist and venture capitalist Bill Janeway, who discusses the new twist the digital revolution has given to the long story of popular anger in American politics. Is inequality driving this anger or is it the quality of the jobs now on offer? And what will happen to those jobs when machines can do them more efficiently?
