这个intragovernmental debt很多是进了股市（花二姐）；

intragovernmental debt is debt that one part of the government owes to another part. In almost all cases, it is debt held in government trust funds, such as the Social Security trust funds. These debts represent assets to the part of the federal government that owns them (i.e., Social Security), but liabilities to the parts of the government that issue them (the Treasury Department). Therefore, they have no net effect on the government's overall finances.
