Evan Davis and guests explore why some bright, talented people try to get rich the wrong way, while others manage to do it within the rules. Guests Barrister, Sara George, a partner at Sidley Austin LLP Michael Corrigan, Chief Executive at Prosper 4 - a training and recruitment firm for former prisoners and Dr Anja Shortland, Reader in Political Economy at King's College, London.
