Newsom’s “Economic Reset”: Tax Hikes Wrapped in Populist Rhetoric

California Governor Gavin Newsom is calling for what he brands an “economic reset for America,” centered on a new national tax aimed at people with net worth over $100 million.^[5] He says he wants a “true minimum tax on billionaires” so that “people at the very top pay at least the tax rate their own workers pay,” a modern version of the old Buffett Rule.^[2] The message is framed as standing up for workers, but the tool he reaches for is always the same: higher federal taxes and more centralized control in Washington.

Newsom also argues that the top 10 percent of Americans own about two-thirds of the nation’s wealth and claims the system is “fundamentally broken.”^[3] He folds this into a call to raise corporate taxes back to pre-2017 levels, reversing President Trump’s first-term tax cuts that helped bring jobs and investment home.^[5] For conservatives who remember how lower, stable taxes fueled growth, Newsom’s plan looks less like a reset and more like a rewind to slow-growth, high-tax policies that punish success and expand federal reach.

From Sacramento to Washington: A Governor Fighting One Tax and Selling Another

The most glaring problem for Newsom is simple: in California, he is actively fighting a state ballot measure that would impose a one-time 5 percent wealth tax on billionaires to fund health care and other programs.^[17] He has said he will vote no on that measure and warns it could hurt the state’s economy and push the wealthy to leave.^[2] In his own Substack post, he admits that everyday Americans cannot “pick up and move to Texas or Florida,” but “billionaires can, and do,” when taxes get too high.^[8]

To get around that, Newsom claims the “fight belongs at the federal level,” where wealth cannot flee across state borders.^[6] He now supports a national minimum tax on fortunes above $100 million instead of the California one-time 5 percent levy.^[5] That split position gives him a way to sound tough on billionaires to a national audience while avoiding the immediate fallout of a California exodus on his record at home. For many voters, that looks less like principle and more like positioning ahead of a possible 2028 presidential run.^[2]

Closing Loopholes or Opening the Door to a Permanent Tax State?

Newsom leans heavily on one real problem in the code: so-called “tax-free lifestyle loans.” He attacks the practice where ultra-wealthy people borrow against appreciated stock portfolios to fund lavish lives while reporting little or no taxable income, then pass those assets to heirs without paying tax on gains.^[8] He calls for ending that strategy and tightening inheritance rules, warning of a $124 trillion intergenerational wealth transfer that could create a “permanent American aristocracy.”^[3] Many conservatives agree loopholes should be fixed, but worry his cure is worse than the disease.

Instead of narrowly targeting abusive schemes, Newsom wants broad new federal powers over wealth itself, including higher corporate rates, new inheritance rules, and aggressive federal minimum taxes.^[5] Free market policy analysts have long warned that wealth and billionaire taxes raise much less money than promised because people change their behavior and move assets or themselves.^[22] Evidence from other wealth tax experiments shows expectations often get cut in half once investors react, even as the tax code gets more complicated and the Internal Revenue Service grows more intrusive.^[22] That is the opposite of the limited, predictable tax system that supports long-term growth.

AI “Public Equity Fund”: Shared Prosperity or Government Ownership?

One of Newsom’s most radical ideas is a national “public equity fund” tied to artificial intelligence.^[8] He says that as AI reshapes the economy, “every American should own a stake in the future it builds” through a federal fund that “takes a major stake in the new economy.”^[5] In practice, that means the federal government would directly own slices of AI and tech firms, then use future gains to fund programs like universal child care, free college, job training, and expanded health care.^[15] That is a huge step toward state-directed capital under the banner of fairness.

For conservatives, this raises serious red flags. Government stakes in key tech companies blur the line between regulator and owner, inviting political pressure on innovation, speech, and hiring practices. It also locks more Americans’ hopes to Washington-managed funds instead of private savings, business ownership, and local opportunity. Newsom offers no clear plan for how the fund would be governed, how shares would be picked, or how ordinary families would truly “own” anything beyond another promise on a federal balance sheet.^[5] That lack of detail matters when trillions and core freedoms are on the line.
