I doubt most people would pass a financial audit, unless they had built their life around "proper accounting controls". Of course, if they had an incentive to do so, it probably would only take two or three years to get things in place and consistent. But then, most people don't have 1.3 Million active employees [1], who knows how many contractors and retirees. The DoD's finances were not designed around audit requirements and it takes time and consistent attention to retrofit accounting controls into a very large organization.
