The federal government keeps two sets of books.
The set the government promotes to the public has a healthier bottom line: a $318 billion deficit in 2005.
The set the government doesn't talk about is the audited financial statement produced by the government's accountants following standard accounting rules. It reports a more ominous financial picture: a $760 billion deficit for 2005. If Social Security and Medicare were included — as the board that sets accounting rules is considering — the federal deficit would have been $3.5 trillion.
