Some info for you about US federal government debt.

• Current "National Debt" $27 TRILLION. This number is ONLY the amount owed by US gov. to US Treasury bond holders/purchases. Individuals, corporations, countries. Does not include unfunded liabilities like SS, Medicare, etc. which equal $156 TRILLION. 
• Again, this info is US federal gov. only (not state or municipal) debt and unfunded (promises to pay but no money in fund to pay for it) SS and Medicare. 
• Does not include unfunded Medicaid funding, government employee pensions (military/federal gov employees), VA medical shortfalls.
