Given that U.S. federal spending always goes up, and inflation always goes up, wouldn't it be the case that every $1T in debt would be accumulated faster than the previous $1T? That's generally how exponential growth works: https://farmdocdaily.illinois.edu/wp-content/uploads/2021/12...
Not to mention population growth. The debt per capita or debt to GDP could be improving (it's not) and we still see headlines like this. It's a fun milestone, but context matters.
