If it did, it should go public and it's IPO would generate massive investments that it could use to get out of debt.
During the initial offering, a massive campaign could be put in place to show people that even with its faults, you can't have a world without the US government in place. The world needs it, depends on it.
That realization alone would be enough to make every investor realize that they HAVE to invest in the US gov't IPO and would guarantee the rise of the stock price.
