Global economist Dambisa Moyo says democracy is in crisis around the world. In her book "Edge of Chaos," she explains how voter participation rates are low, money is seeping into politics via big donations, and political freedoms have declined. "We do have democracy on paper, but in terms of the efficacy and efficiency of the democratic process, I think there are deep concerns," Moyo says. In her conversation with guest host and journalist Susan Page, she also describes the hurdles she’s overcome to work in a field dominated by men.
