Maybe I shouldn’t be drinking beer while working on a lesson, but what does it mean that the Federal Government held 4.6 trillion of the debt in 2011? Oh, are those the IOUs, like for Social Security?
This website breakdown the federal debt by who holds it. Of the $16.7 trillion in U.S. Treasury debt, $11.,9 trillion is held by the public and $4.8 trillion is “intergovernmental holdings.”
