When The U.S. Paid Off The Entire National Debt
On Jan. 8, 1835, all the big political names in Washington gathered to celebrate what President
Andrew Jackson had just accomplished. A senator rose to make the big announcement: "Gentlemen ... the national debt ... is PAID." That was the one time in U.S. history when the country was debt free. It lasted exactly one year. The legend of the
national debt and where the debt came from. What happened the one time we paid it all off and why Congress created the
debt ceiling in the first place?
