CNN's John Sutter talks with author Michael Wolraich about his new book, Winner Cells All. The title seems to reflect both Amazon and Walmart: They want to sell everything but at the same time, there're going to be many winners in e-commerce. "We might not be in a great position as a society if there's only one," says Wolraich. 'Even these two goliaths going head to head, their competition is probably not enough'
