Bullwinkle, sorry, I did not have a chance to proof that post, here is a better version:
Have you ever tried to calculate the assets the "government" owns?. In that respect, respect the government's books are much more conservative than corporations. We do not amortize capex, we expense these as they come. The books include absolutely no goodwill. And real estate is carried, in most cases at a zero value. If absolutely necessary, the "government" could sell few airports, few buildings, few national parks", maybe few thousands miles of interstate highways and cover its deficit. I doubt that such a default is in the cards, that is why most of the world likes the dollar.
