In Arriving Today: From Factory to Front Door—Why Everything Has Changed About How and What We Buy, Christopher Mims announces his goal up front: to convince you of "this astonishing fact: You live inside a factory. We all do. And you are also a worker inside that factory." Although Arriving Today doesn’t quite end up making that argument, it paints a compelling picture of the elephantine supply chain that delivers products to our doorsteps. Needless to say, its publication is timely.
