Deficit worse than it looks due to accounting tricks

From Chron.com:

President Lyndon Johnson, to make the deficit numbers during the Vietnam War less scary, adopted the "unified budget," under which Social Security's surplus was mingled with general revenues, thereby reducing disguising, really the deficit's size. That, Cooper says, was the "original sin" in the budgeting sleight-of-hand that prevents the public from knowing, and Congress from being compelled to act on, facts about the entitlement programs' unfunded liabilities promises to future beneficiaries that future taxpayers may not be willing to pay.

Under such accounting, future outlays to which beneficiaries are entitled by existing law are acknowledged as expenditures before they are paid. Were the Social Security surplus sequestered for accounting purposes, reflecting the truth that it is already obligated, and were there similar treatment of the other entitlement programs' liabilities, the deficit for the fiscal year that ended Sept. 30 would have been $3 trillion rather than $454.8 billion. The report's numbers show that the true national debt is $56 trillion, not the widely reported $10 trillion.
