How people discuss the US national debt is an interesting case study of misleading usage of the wrong statistic. The key thing is that people discuss the raw debt amount and the rate at which that is increasing, but you ultimately care about the relationship between debt and US gdp (or US tax revenue).
People often talk about needing to balance the budget, but actually this isn’t what you need to ensure[1], to manage debt it suffices to just ensure that debt grows slower than US GDP. (And in fact, the US has ensured this for the past 4 years as debt/GDP has decreased since 2020.)
To be clear, it would probably be good to have a national debt to GDP ratio which is less than 50% rather than around 120%.
There are some complexities with inflation because the US could inflate its way out of dollar dominated debt and this probably isn’t a good way to do things. But, with an independent central bank this isn’t much of a concern.
the debt/gdp ratio drop since 2020 I think was substantially driven by inflation being higher then expected rather than a function of economic growth—debt is in nominal dollars, so 2% real gdp growth + e.g. 8% inflation means that nominal gdp goes up by 10%, but we’re now in a worse situation wrt future debt because interest rates are higher.
