It looks like the U.S. government keeps borrowing money from foreign investors with no intent or ability to pay it back. My question is: how would I capitalize on this notion? Would I short bonds? T-bills? I'm relatively new to trading so I'm not aware of all the nuances and intricacies of the loan market. But it seems logically impossible for the U.S. to keep this up forever. The only way I can see this as not happening is for Congress to balance the budget (which is impossible for the next few years under Obama's 'rescue' plan) or China keeps lending indefinitely. Have investors already reached a consensus on this?
