Le discours fiscal qui pourrait signifier la "fin de l'Amérique"

California voters face a critical decision next month regarding Proposition 40, a ballot measure proposing a one-time 5 percent tax on the net worth of the state’s billionaires. A new working paper from Stanford University researchers suggests the initiative could ultimately cost the state approximately $39 billion in lost revenue, significantly outweighing the funds it would initially generate. The study indicates that 85 percent of plausible economic scenarios result in a net loss for California due to the departure of wealthy residents. The research, authored by Benjamin Jaros and Joshua Rauh, projects that the tax would yield roughly $30 billion, a figure far below the $100 billion estimate supported by the measure’s proponents. The discrepancy arises because many high-net-worth individuals have already begun relocating. Seven billionaires have publicly announced their moves out of California, representing more than $539 billion of the state’s nearly $1.9 trillion aggregate billionaire wealth. These departures include venture capitalist Peter Thiel and Google co-founders Larry Page and Sergey Brin. Because additional exits are likely occurring privately, the effective tax base has shrunk considerably before the vote takes place. While $30 billion constitutes substantial immediate revenue, the long-term financial impact appears negative. The researchers estimate that California stands to lose between $1 billion and $3.5 billion annually in income taxes as its resident population becomes less wealthy. When discounted to present value, these perpetual income tax losses exceed the initial wealth tax proceeds by about $39 billion. Jaros and Rauh concluded that the behavioral response of taxpayers has eroded most of the projected tax base, meaning the act will not fulfill its primary design function of raising sustainable revenue. The ballot measure aims to shore up California’s healthcare system, a goal championed by the Service Employees International Union-United Healthcare Workers West, the union that introduced the proposal. Debru Carthan, vice president of the local union, dismissed the academic findings as part of a misinformation campaign. She stated that the sole purpose of the tax is to ensure billionaires pay their fair share to prevent a collapse of the state’s healthcare infrastructure. Carthan asserted that California residents see through such arguments, maintaining that the measure is necessary for fiscal stability. Political divisions within the Democratic Party have intensified over the issue. Governor Gavin Newsom opposes Proposition 40, having previously attempted to keep the state-level version off the ballot. However, following his failure to block the measure, Newsom expressed support for a national billionaire tax. Conversely, Representative Ro Khanna, a progressive Democrat from California, described the initiative as the most important ballot measure in the country and a fight for the soul of the party. Polls indicate that voters are narrowly split on the issue. A recent survey found 46 percent of respondents planning to vote for the measure, while 43 percent opposed it. Critics outside the state have also weighed in on the concept of wealth taxation. United Airlines Chief Executive Officer Scott Kirby recently advocated for both national wealth and inheritance taxes, arguing that wealth inequality poses a danger to society. He suggested that inheritance taxes approaching 100 percent for certain estates could help level the playing field. Investment banker Lou Basenese countered that such policies could signal the end of the American economic model. Basenese warned that wealthy individuals would seek loopholes or relocate, discouraging others from pursuing financial success. He noted that many of the wealthiest Americans, including figures like Warren Buffett and Bill Gates, already donate large sums voluntarily. Historical precedents suggest that capital mobility undermines static wealth taxes. In Washington State, the introduction of a new wealth tax prompted Jeff Bezos to relocate to Florida, while Starbucks shifted portions of its corporate headquarters to Tennessee. Similar trends followed a millionaire tax in Massachusetts. Internationally, several nations have abandoned similar levies. France eliminated its wealth tax in 2018, replacing it with a narrower real estate levy. Sweden scrapped its wealth tax in 2007. Last year, Swiss voters rejected a 50 percent inheritance tax on estates exceeding $62 million. Basenese argued that the liquidity constraints of the proposed California tax would disproportionately affect Silicon Valley startup founders whose wealth is tied to illiquid private equity. He contended that forcing payment based on paper valuations amounts to confiscation rather than taxation. Instead of government intervention, he pointed to employee ownership programs at technology firms as evidence that capitalism can distribute wealth effectively. For instance, he cited Nvidia, where 25 percent of employees are currently millionaires. The debate continues as the election approaches. While proponents view the tax as a necessary correction to systemic inequities, opponents argue it drives away the talent and capital essential for economic growth. The Stanford study adds quantitative weight to the argument that the measure may fail to achieve its fiscal goals. With polls showing a tight race, the final outcome will determine whether California implements the tax or avoids the predicted revenue erosion. The results of the upcoming vote will serve as a test case for the viability of state-level wealth taxes in the current economic climate.
