We spent $124.409 billion
and only $2.542 billion was spent on federal salaries.
Did the rest go to al Qaeda?
I agree, this is the worst explanation of finances I have seen. We are left to assume that the 124.4 billion expenditures were SS & Medicare payouts, or bond interest payments. Maybe Retirement payments or disbursements to state and local governments. It could be just about anything with the unconventional way the feds keep OUR books.
Salaries are a trivially small part of the total cost of government. Most of it goes to either contractors, various forms of aid payments, and purchasing stuff.
