Accounting is an Inexact Science?

In order to try to brush off criticism from his administration creating jobs in nonexistent districts, Obama just called accounting "an inexact science." What a load of bull. There are certain aspects of accounting which do require assumptions and are inexact (e.g. depreciation schedules, cost accounting), however in this case, all they are trying to do is count how many beans went where. There is absolutely nothing complicated in that. Just figure out where the money went. Can you imagine if CEO's under investigation from the SEC started quoting Obama on this? The idiotic things that come out of this guy's mouth are breathtaking.
