Public debt includes not only the federal government’s current $13.2 trillion, but another $3 trillion owed by America’s states, counties, and cities. In addition, there is the $3.9 trillion in debt owed by America’s government-backed housing-finance agencies (Fannie Mae, Freddie Mac, and others), which currently underwrite more than 90% of all US mortgages.
美国的债务总额令人震惊。其公共债务不仅包含了联邦政府的13.2万亿美元债务，还包含了由国内各州以及各县市所欠下的3万亿美元，此外还要加上那些有美国政府背景的房屋信贷机构（房地美，房利美等）的3.9万亿美元欠款——这些机构目前承担了全美超过90%的抵押贷款。把上述数字都加在一起之后，美国的公共债务总额几乎等于其GDP的140%
