Hour 2: What’s driving adult children back into their parents’ homes across the developed world and what are their future prospects for economic independence? We’ll talk this hour with Katherine S.

She writes about the phenomenon and its effects in her new book “The Accordion Family: Boomerang Kids, Anxious Parents, and the Private Toll of Global Competition” (Beacon Press, 2012).
