Our debt is to the FED, a private banking cartel. The FED creates fiat money out of thin air. The US must pay it back with interest. The interest must be created out of thin air and borrowed from the FED. It has been proposed that the US repudiate its debt to the FED and eliminate the Central Banking system. It could go back to a precious metal based system - with a block chain component and a Treasury Note component.
There needs to be some sort of transition or reset or debt Jubilee for the economy to recover and resources invested back into a productive free market. Of course, you then have problems with aiding the elderly to live if they are unable to work. A lot of paper wealth would go with the FED, but so would the debt.
You can’t sell a lot of the “Public Land.” It has private split estate mineral, grazing and right of way property rights associated with it. They tried to do that once before. There is also questionable title to the lands (fed or state.)
