What is the national debt?
As of June 4, 2018, the total outstanding debt owed by the federal government was $21,090,788,185,039.90, or $21.1 trillion. “It is mostly an abstract concept, unlike, say, a personal student loan or auto loan or mortgage, where you have a personal obligation to repay the debt,” said White. For an individual, the national debt has none of those particular characteristics.
