The most widely acknowledged financial effects of 9/11 on the US is that it prompted an enormous boost in government spending on Homeland Security and it convinced the citizenry to permit expensive military occupations in Afghanistan and Iraq. This has all been paid for with borrowed money, and has contributed to the national debt. But did 9/11 have a wider effect on the US economy than helping to swell an already broken budget? Is 9/11 a critical root of the current economic condition in America?
Was 9/11 a big splash the waves of which have long settled, or was it a rock to the windshield that's been cracking to this day?
