It is too early to evaluate this prediction.

The claim is that “the only stopgap in the next decade is going to be significantly higher tax rates in the United States” on corporations and high‑net‑worth individuals, as the primary way to deal with fiscal pressure from debt and entitlements, with a horizon of roughly the next decade from 2023 (i.e., around 2033).

As of November 30, 2025, several points hold:

• The core elements of the U.S. federal tax code affecting corporations and high‑income individuals (e.g., the 21% statutory corporate tax rate set by the Tax Cuts and Jobs Act, top individual brackets) have not undergone a large, clearly debt‑driven hike of the sort described. Proposals by the Biden administration to raise corporate and high‑earner taxes (e.g., higher corporate rate, minimum tax on billionaires) have either been scaled back or stalled in Congress, and have not produced a sweeping, clearly dominant fiscal response to debt/entitlement pressures.
• U.S. fiscal stress from debt and entitlement spending is well documented and growing, but there has not yet been a decisive policy turn in which significantly higher taxes on corporations and high‑net‑worth individuals are adopted and recognized as the primary stopgap for these pressures.

However, the prediction’s time window extends out to ~2033, and tax policy can change substantially in election years or around scheduled expirations (e.g., the 2017 tax cuts that are due to sunset after 2025). Until that full period has elapsed, we cannot say whether the U.S. will or will not ultimately adopt such significantly higher tax rates as its main response to fiscal pressures.

Because the forecast is explicitly about what will happen over the coming decade, and we are only about 2.5 years into that period, the correct status classification is “inconclusive (too early).”
