We owe $19 trillion but that doesn't include the over $100 trillion in unfunded liabilities, i.e., the entitlement programs. And what happens when interest rates return to normal levels and our debt servicing costs soar consuming even more of the federal budget. The entitlement programs, other mandatories like Medicaid, food stamps, etc, and debt servicing costs consume more than two thirds of the budget now. Those costs will go up as the population of those over 65 doubles over the next 15 years.
