Taking in depression and prosperity, this edition of the Kiwi social history series explores the boom and bust cycles of the economy. Stories include TJ Edmonds, of baking powder fame, who made his fortune by hawking his wares around Christchurch before opening his iconic factory. Factory workforces expanded, and with them unions. Worker dissatisfaction with pay and conditions led to the Queen Street riot of 1932, a defining moment in NZ history retold here by protest leader Jim Edwards' son. Edwards’ real estate agent granddaughter is also interviewed.
