you have a fundamental misunderstanding of govermental debt and the US.the US CAN 100%, its not a guess its a fact, spend away their troubles forever.
learn how the global economy is, understand what fiat is, find out what your missing. (first hint, money is a construct - and follow the tbills)
you know what does make the US have to do "painful austerity measures - budget cuts, increased taxes, and the like. It's unpopular to do painful things, but it's necessary for survival" ??
Watch everything the current administration does because they dont understand modern economics and you'll see.
