In the past fifty years, wealthy nations including the U.S. have given $1 trillion in aid to the continent of Africa. And yet, many African countries remain mired in poverty. So is it time to rethink aid to Africa? The Takeaway talks to Dambisa Moyo an economist and author of the book Dead Aid: Why Aid is not Working and How there is a Better Way for Africa. We are also joined by Lynn Sherr, journalist and Africa correspondent for PBS’s World Focus.
