Is $4 Trillion the present value of all future cash flows that the US represents? If so, the US should buy this bargain basement deal and then tax Rest-of-World into oblivion. The world's last remaining engine of innovation -- driven by champion of individualism -- is priceless. The global ecosystem needs a driver, and for better or worse it's the USA. Don't worry, folks, the USA is in slow decline... it's likely that someday soon we'll all enjoy the pleasure of being equally poor in the fairest of all global societies. Extraction of bullshit penalties like this would certainly hasten the socialist, commie-bastard fantasies that illustrate man's fatal flaw: the combination of a sense of superiority, entitlement, jealousy, and sloth that subverts individualism and champions equality. Fuck if these mythical agrarian societies have been so wronged, tell them to turn in their cell phones, learn to speak Japanese, German, Chinese or Russian, decimate their populations, and we'll talk about the balance of their account. Bite me.
