Naomi Klein and Ilana Glazer, writing in the Guardian, argue that billionaires are growing vastly richer while ordinary Americans struggle, and urge taxing billionaires — starting with wealth taxes in California and New York — and blocking the impending IPOs of Anthropic and OpenAI. They say SpaceX's public listing made Elon Musk an instant trillionaire, cite Sergey Brin's $100m against California's Prop 40, and warn that when the AI bubble bursts it will take everyone with it, investors or not.
