This should be much more concerning:
Oct. 17 Debt ceiling vote far more disconcerting than shutdownFailure to raise the debt ceiling will result in an essentially much worse shutdown, as the government will literally lack even the most basic of provisions deciding what to keep running - unlike now, where law dictates that certain services, such as police forces, must remain in effect. Thus, no one will be paid, and all government services are at risk of shut down.
A debt ceiling breech has never occurred before, while shutdowns were relatively common in the 1960s and 70s. This is reflected in the lack of contingency plans for a debt ceiling breech, while a shutdown is quite organized.
Furthermore, a default on international loans will permanently raise America's interest payments. An increase of 0.1% equates to approximately 85 billion USD in interest payments per year.
If you think this is infeasible, keep in mind that Tea Party leaders such as Marco Rubio
have stated that the strongest GOP push against the Affordable Care Act is to occur over the debt ceiling, as it is believed Obama cannot afford a default and will thus be forced to concede.
