"Our market system has been ripped out of any democratic boundaries," says Frances Moore Lappe. She says the top three wealthiest Americans now control more wealth than the bottom half of Americans combined. Frances believes this is because we have accepted materialism, selfishness and competition as the defining characteristics of being human, and ignored our capacity for empathy and cooperation. She cites a study showing that "when humans cooperate, our brains react as if we're eating chocolate -- it's that pleasurable," as evidence to the contrary. Today, we're pleased to share this episode with award-winning author and activist Frances Moore Lappe, whose latest book addresses the importance of reclaiming democracy and embracing cooperation.
