If U.S. federal debt rises to around 200% of GDP with interest rates around 4% (implying roughly $2 trillion in annual interest expense at current GDP levels), then to sustain that debt service the U.S. will eventually raise overall tax burdens so that effective tax rates exceed 70% of government income (i.e., taxes will need to be raised to historically high, roughly 70%-plus levels).
You're using more than half of the government's income based on the current tax rates to fund the interest payments on your debt. That's not even to pay for social services... That's just more than half of the income... That's why you have to see taxes go up to over 70% because it's the only way you can. You got to tax everything in order to fund that.View on YouTube
Explanation

As of November 30, 2025, the conditions in Friedberg’s conditional prediction have not occurred, and the prediction is explicitly about what will eventually happen if those conditions are met.

Key facts:

  • Debt-to-GDP has not reached ~200%. Gross federal debt is around 119–125% of GDP in 2024–2025, well below 200%.(pewresearch.org)(tradingeconomics.com)(fiscal.treasury.gov) Treasury’s long‑term projections suggest debt might exceed 200% of GDP around mid‑century (e.g., by 2049) under unchanged policy, but that is a projection, not a current reality.(fiscal.treasury.gov)(fiscal.treasury.gov)
  • Interest costs are far below the implied ~$2T and <50% of revenue. Net interest outlays are just under $1 trillion per year as of FY 2025, not $2T, and amount to roughly 14–19% of federal revenues, not “more than half.”(gurufocus.com)(debt-clock-usa.com)(siai.org)
  • Tax burdens are nowhere near the “70%+” level he describes. Federal receipts are about 17% of GDP in 2024, in line with historical norms.(bidenwhitehouse.archives.gov)(ycharts.com)(gurufocus.com) The top marginal federal income tax rate is 37%, and overall federal, state, and local tax collections are on the order of a few tens of percent of GDP, not 70%.(eitc.irs.gov)(pgpf.org)

Because:

  1. The triggering scenario (debt ≈ 200% of GDP at ~4% rates, with interest consuming over half of government income) has not yet occurred; and
  2. The prediction is about what will happen eventually under that future scenario (no specific deadline),

there is not yet a factual basis to say whether his claim about future 70%+ tax burdens is right or wrong. It remains a theoretical, forward‑looking argument about fiscal arithmetic and political choices. Therefore, the status of the prediction is inconclusive (too early to tell).
