Jason predicted that in the coming years the U.S. would (1) force people to publish their tax records and (2) impose some kind of minimum/wealth tax on large asset holders.

1. Public disclosure of individual tax information
Federal law still treats individual tax returns as strictly confidential under Internal Revenue Code §6103, and IRS guidance emphasizes that returns and return information may not be disclosed except in narrow, codified circumstances. The Freedom of Information Act and other open‑government rules explicitly do not override these protections. (irs.gov)
Recent developments reinforce privacy rather than moving toward public release: in 2025 a federal court ruling highlighted that tax data remain highly protected and rejected broader sharing of IRS information, underscoring the importance of confidentiality. (washingtonpost.com)
No federal statute or regulation has been enacted since 2021 that mandates public disclosure of ordinary individuals’ tax returns or even high‑level summaries. State-level attempts have been narrow (e.g., California’s law conditioning candidate ballot access on releasing tax returns, parts of which were struck down) and do not create general public disclosure for taxpayers. (en.wikipedia.org)
Net effect: U.S. policy has not moved toward forcing taxpayers in general to publish their tax records; if anything, legal and judicial actions have reaffirmed confidentiality.

2. Minimum tax / wealth tax on individuals with large holdings
The U.S. still has no federal wealth tax—there is no ongoing annual tax on individuals’ net worth. Major tax-policy summaries as of 2025 explicitly state that the United States does not impose a federal wealth tax, and no state currently levies a recurring net‑wealth tax on individuals either.

There have been proposals aimed at very wealthy individuals—e.g., the Ultra‑Millionaire Tax Act of 2021 (a true wealth tax) and the Biden administration’s “Billionaire Minimum Income Tax,” which would apply a minimum rate on very high‑wealth households including unrealized gains—but these remain proposals, not enacted law. (en.wikipedia.org)
At the same time, Congress has moved in the opposite direction on some wealth-related taxes, such as advancing legislation to keep or raise very high estate‑tax exemptions, which eases taxation of large inheritances rather than tightening it. (washingtonpost.com)
Some states, like Washington, have floated wealth‑tax bills, but as of late 2025 these remain proposals and have not established an operative wealth tax regime. (apnews.com)

Conclusion
More than four years after the June 2021 podcast, the U.S. has not begun forcing public disclosure of individuals’ tax records, nor has it adopted any form of federal wealth tax or mandatory minimum tax specifically targeting individuals’ net worth. Policy discussion has occurred, but the concrete legal changes Jason predicted have not materialized, and in some respects policy has moved the other way. Therefore, the prediction is wrong.
