You make some good points on whether we can grow out of this or not. My example was perhaps too extreme. If we even grow one percent above the growth in the deficit is does help. I really think that is doable. AI might just be the catalyst. Others could be electric battery breakthroughs, medical breakthroughs, etc. I admit too that a recession or depression could also come along and the negative growth could make the US public debt soar. So you are right too in that soon is the time to make the changes to reduce the deficit. I say soon because the USA may technically already be in a recession or will be soon. Austerity policies are not going to work well if we are in a recession.Growing our economy faster than the deficit may seem like a simple solution—but is it realistic?
We have indeed done what you suggest before. After World War II, our national debt was above 100% of GDP, but we simply grew out of it. That’s the staggering power of exponential growth. If the economy grows steadily each year, it can become massively larger over time and eventually dwarf the debt accumulated during earlier years.

But can we do that again?
I’d love to believe that our economy could double, and then double again (and again), until the debt-to-GDP ratio becomes minimal. But that doesn’t seem practical anymore. The post-war economic boom was fueled by massive supplies of cheap oil, coal, natural gas, and minerals. We've already used up much of the easiest and cheapest of those resources. What’s left is harder to extract, more expensive, and increasingly subject to geopolitical tension and environmental limits.
Expecting endless growth on a finite planet is, frankly, madness.
If we can no longer rely on exponential growth to shrink our debt burden, we may need to reconsider the alternative: balancing the budget—or even running a surplus.
Should we bet that exponential growth will continue for decades to come—making the national debt a minor concern—or should we begin taking serious steps to reduce it now?
I also am unsure that the GOP or even Trump is committed to deficit reduction. Already there are calls to expand the debt limit by another 4 trillion. Until there is a collapse of debt in some major nation, I think that the politicians will not cooperate. At what level is the collapse likely? Impossible to say. I can remember reading Federal Reserve articles twenty of more years ago that worried about 100 % of debt to GDP ratio. Well that sure was wrong. Likely it is whatever sets a panic in motion. That panic could be a war, disaster, lower sustained GDP but the result will be inflation expectations that are severe and the hurt will be evident. I still think Japan is the most likely modern nation to crack but the catalyst to bust could come from one nation, to many.
Your chart shows it great too, the debt to GDP at the end of WWII. Now that the USA is at the same % levels as the end of WWII, what would happen if there is a serious war?
Thus, it is totally reckless that we allowed this much debt. Every nation needs some slack in debt in case of an emergency. The USA has very little if any room for error.
