When $38 Trillion Isn’t Just a Number: How America’s Debt Could Tip the Generational Scales
We love big round numbers until they start deciding our futures. $38 trillion is one of those numbers — headline-grabbing, slightly abstract, but increasingly real for anyone trying to buy a home, save for college, or imagine retirement. A recent think‑tank note picked up by Fortune warns that America’s mounting national debt won’t fall evenly across the population: it will weigh on younger generations the most. That warning deserves a closer look.
A quick, human-sized snapshot
- The U.S. federal debt has crossed the $38 trillion mark in 2025, a milestone reached faster than many expected. (fortune.com)
- Rising interest costs are already a major budget item; they threaten to crowd out spending on education, infrastructure, research — things that boost long‑term prosperity. (fortune.com)
- Jordan Haring, director of fiscal policy at the American Action Forum, warns that these developments exacerbate generational imbalances, shifting costs onto millennials, Gen Z, and future workers. (fortune.com)
Why generational imbalance matters (and why this isn’t just political theater)
Think of the federal budget like a household budget that’s borrowed to stay comfortable. When debt servicing (interest) grows, less is left for investments that raise future incomes — schools, roads, basic research, child care supports. The American Action Forum’s analysis, cited in Fortune, makes three linked points:
- Higher interest costs mean a bigger share of tax dollars goes to past borrowing instead of future growth. (fortune.com)
- Demographic trends (aging population, lower birth rates) increase pressure on entitlement spending while shrinking the relative size of the workforce that finances those promises. (fortune.com)
- If policymakers don’t change course, younger cohorts will face either higher taxes, reduced benefits, or both — plus slower wage growth if public and private investment is crowded out. (fortune.com)
That dynamic creates a policy trap: politically powerful older voters push to preserve benefits earned under prior rules, while younger voters—who will carry the fiscal burden—have less political leverage today.
The mechanics: how debt becomes a generational problem
-
Interest and crowding out
As the debt rises, interest payments climb. Those dollars are fungible: every extra dollar to interest is a dollar not available for things that foster growth. Over time, that constraints opportunity for younger workers. (pgpf.org) -
Demographics and entitlement pressure
Medicare and Social Security scale with an aging population. With fewer workers per retiree, the math becomes harder: either taxes go up or benefits are trimmed — both outcomes bite future generations. (fortune.com) -
Market reactions and macro risks
If debt grows faster than the economy for long, lenders demand higher yields; that raises borrowing costs across the economy (mortgages, business loans), slowing growth and wages — again, a heavier share of the pain lands on those just starting their careers. (fortune.com)
Contrasting views and caveats
-
Not everyone frames the problem the same way. Some economists emphasize growth, inflation dynamics, or monetary policy as the bigger risk drivers rather than demographics alone. High public debt is a vulnerability, but timing and severity of consequences depend on policy responses and macro conditions. (fortune.com)
-
The American Action Forum is a conservative-leaning think tank; critics have disputed past estimates and assumptions. That doesn’t negate the underlying concern — high debt creates constraints — but it does mean projections depend heavily on assumptions about growth, interest rates, and future policy. (fortune.com)
What policy options could ease the burden?
- Slow debt growth through a mix of spending restraint and revenue measures, ideally spread across program areas so the cost is shared rather than concentrated. (pgpf.org)
- Re-target or reform entitlement rules to stabilize long‑term obligations (gradual retirement‑age adjustments, means‑testing, or benefit formula tweaks). (fortune.com)
- Invest in growth-enhancing priorities (education, infrastructure, research) to raise future GDP and improve the debt-to-GDP picture without purely austerity‑style measures. (fortune.com)
None of these are politically painless. Each redistributes costs across time, income groups, or generations — which is why agreement is hard to come by.
What young people (and their allies) should watch for
- Budget tradeoffs: are rising interest payments displacing education and infrastructure? (pgpf.org)
- Tax policy design: whether reforms are progressive or regressive will determine who bears new burdens. (fortune.com)
- Long-term commitments: look at whether short-term fixes are crowding out durable solutions that protect future generations’ economic mobility. (fortune.com)
A few practical questions worth asking policymakers
- How will proposed fiscal plans change debt trajectories over the next 10–30 years?
- Which public investments are being prioritized or cut as interest costs rise?
- Do revenue measures shift the burden toward future workers or distribute it more evenly across incomes and ages?
My take
Numbers like $38 trillion can feel distant, but the policy choices we make now determine whether that sum acts as a drag on future opportunity or a problem we responsibly manage. The American Action Forum’s warning — that younger Americans will disproportionately shoulder the cost — is persuasive in its logic even if specific projections vary. If we want a fairer fiscal future, conversations about debt can’t remain technocratic sidebar arguments; they must center the people who will live with the bill longest.
