Sangu Delle: In praise of macro -- yes, macro -- finance in Africa

In this short, provocative talk, financier Sangu Delle questions whether microfinance — small loans to small entrepreneurs — is the best way to drive growth in developing countries. "We seem to be fixated on this romanticized idea that every poor person in Africa is an entrepreneur,” he says. "Yet, my work has taught me that most people want jobs.” Delle, a TED Fellow, makes the case for supporting large companies and factories — and clearing away the obstacles to pan-African trade.
