The US owns about 65-70 percent of the land in the country. How much is that worth? We have over a trillion barrels of oil locked up in shale rock on government land. What is that worth.
The several states and the US controls 100% of the land and resources on behalf of its citizens.
In any case, who am I to disagree with this very detailed and sourced paper? The US must be bankrupt if the author says so. Therefore, my offer stands. Send me your good for nothing, now worhtless T-bills, bonds and paper currency and I will do you a favor by giving you 10 cents on the dollar. But this offer is only good for a limited time.
At today's prices - 70 trillion dollars. Hell, that even leaves a little money left for reparations...
