Cowen argues that global trade and communication are enriching all the world's cultures and that there's no such thing as cultural authenticity. . . . In fact, Cowen believes that commerce and art are allies. And he contends that because commerce is driving technology, ideas, goods, services and people across borders more freely than ever before, we are in the midst of an unprecedented boom in creativity all over the world. The quality, quantity and variety of cultural output is greater than ever; if there is more dreck, there is also more genius. And more people have more access to it than ever, at lower prices, regardless of where they live.
