Amazon. Failing infrastructure that other companies rely upon and expect to function adequately, will not pose the same challenges. They deal with the logistics of delivering items of necessity to people all over the globe at enormous scale. They have their own fleets, their own delivery people, and their own automation approach. In a decade Amazon won't need the post office or UPS. The barriers to entry in taking that on are enormous to the point of near impossibility. Heck, even their ability to sell counterfeit garbage to customers without significant penalty on themselves shows they even know how to disappoint people correctly...

Good points, I wonder what a government run by Amazon would look like...
