I think the problem (and I use that word deliberately, because I think it *is* a problem) is that our government doesn't work like your normal family or business. Congress spends, then the Treasury has to find ways of paying the bill. It'd be like giving your son a credit card and he buys a Mustang, two trips to Vegas and a complete first edition of the Encyclopedia Britannica, then you have to pay the bill. This is money already spent - hours worked by people, contracts entered into, facilities and bombs built or being built, etc., etc., etc.
The real problem is that Congress, in its infinite ass-hattery, won't sit down and create a budget. They haven't passed a budget in over three years. They are using faux outrage over the Affordable Care Act as a smoke-screen for the real issue, which is we're nowhere near a budget. If they shout & scream about the ACA loud enough, they think the country is stupid enough (and I'm afraid we might be) to not realize that we're at this debt ceiling because they haven't sat down, cut what we can't afford (more bombers) to take care of our responsibilities (making sure our citizens are well-cared for).
