Rich and frugal?

Why do some of the super rich describe themselves as frugal? Is it something about the inner psyche that makes us natural savers or spenders? Elizabeth Hotson speaks to Dolly Parton, who despite earning millions, doesn’t particularly enjoy spending it. We also hear from Karam Hinduja, banker and scion of the billionaire Hinduja family. Tech entrepreneur, Richard Skellett tells us why he sees being wealthy as a responsibility, plus we hear from big savers, Tim Connor and Francesca Armstrong. We're also joined by Sarah Fallaw, author of The Next Millionaire Next Door, Rachel Sherman, author of Uneasy Street: The Anxieties of Affluence and Elin Helander, behavioural economist, neurologist and Chief Scientific Officer at Dreams, a money-saving app. Producers: Elizabeth Hotson and Sarah Treanor.
