Amazon's edge isn't in shipping. It's in fulfillment. Fulfillment By Amazon (FBA) is a boon for many businesses, as it combines warehousing, packing/labelling, and shipping into a single interface at an attractive price. Let's not forget that they also bring customers and handle the entire billing operation, too. If Amazon does harm FedEx/UPS, it won't be by starving them of packages directly, but rather by sidestepping their business, attracting companies to FBA, so that they never enter the "shipping" business sector. I don't expect to see Amazon enter the point-to-point shipping business anytime soon.
