Google co-founder Sergey Brin spends $100M to fight California wealth tax · 1 source tracked

Google co-founder Sergey Brin has donated over $100 million to oppose California's proposed wealth tax, Proposition 40. This tax, if passed, would impose a one-time 5% levy on the state's wealthiest individuals, potentially costing Brin over $13 billion. Brin, along with other billionaires like Eric Schmidt and Peter Thiel, argues that such a tax would harm the state's economy and drive away investment, with some, including Brin himself, reportedly relocating their residency to states like Nevada.
