Mark Cuban just torched California’s proposed wealth tax in a public exchange with Rep. Ro Khanna, and the fireworks are worth watching for anyone who still believes the Second Amendment can survive a government that can simply confiscate your assets. Cuban’s core point was blunt: once politicians can reach into your brokerage account or private-equity stake every year, the same machinery can be aimed at anything else you own—your gun safe, your reloading press, your land where you hunt. A wealth tax isn’t just a soak-the-rich scheme; it’s a permanent, rolling inventory of every dollar you have, and that inventory becomes a target list the moment the political winds shift.
The exchange also exposed the bait-and-switch at the heart of “tax the billionaires” rhetoric. Khanna framed the levy as painless for the ultra-wealthy, yet Cuban countered that the real cost lands on employees, vendors, and the small businesses those billionaires bankroll—many of them in red-leaning counties that still make their living from manufacturing, energy, and agriculture. For the 2A community, that matters because the same counties are home to the bulk of domestic firearms production and the ranges where new shooters learn the ropes. When capital flees high-tax states, the infrastructure that supports lawful gun ownership follows, leaving behind shuttered factories and empty retail space that once hosted the local gun shop.
The deeper implication is constitutional, not just economic. If a state can assess a yearly percentage on every asset above an arbitrary threshold, it can later decide that certain assets—say, “assault weapons” or standard-capacity magazines—are valued at zero or taxed at punitive rates. That turns the tax code into a back-door registration and confiscation system without ever touching the Second Amendment’s text. Cuban may not have framed the argument in those terms, but his warning that wealth taxes invite endless political score-settling is exactly why gun owners should treat every new levy on capital as a live-fire exercise for the next restriction on the right to keep and bear arms.
