how can the country with so many banks, so much foreign investment (inflow of their same currency) and the exorbitant privilege in terms of currency could go bankrupt? just borrow from the banks, if not borrow from the open market in the form of bonds, everyone will rush to buy them, the demand for them is as good as demand for money at large in any nation. the country is a also a top capitalist nation, no signs of degrading magically or stopping the growth so even a larger debt than japan's in terms of gdp could get managed but it won't get that far.
