Defaulting on any debt is irresponsible, especially in the context of an arbitrary debt ceiling. Congress uses these manufactured debates on the debt ceiling as a platform to mime fiscal responsibility while not actually doing anything to tame borrowing. As everyone should be aware, the debt ceiling is related to funding past obligations, which have all been legislated by congress. Any future spending would follow the same process. If deficit hawks in the republican party would like to reduce borrowing, they have the power to do so as they control both houses of congress and the White House. Any grandstanding over the debt ceiling is deceitful and irresponsible.
