The USA, however, has sufficient assets to cover all of its debts and future expenses for the next century.
No. We don’t.
As I understand it, our total worth in the middle of the last decade was about $43 trillion, while our estimated debt is about $222 trillion, when unfunded liabilities are factored in, so no, we do NOT have enough assets to cover our debts, as far as I know, unless you’re counting the natural resources that the environMENTALists are refusing to let us exploit. Then, maybe so, but I doubt it.
