Why do people spend extraordinary amounts of money on objects that seem to serve no practical purpose? And what exactly separates luxury from quality?

Inspired by the case of former SNP chief executive Peter Murrell's misuse of party funds for high-end personal purchases, Fraser, Nick and Peter use a series of examples to explore the deeper psychology of luxury.

The conversation moves beyond political scandal into philosophy, economics and psychology, asking why humans are drawn to unnecessary things, whether luxury serves a genuine purpose, and where the line lies between excellence, indulgence and excess.
