Taxing Silicon Valley’s Wealth: Joshua Rauh on California’s Billionaire Tax Initiative

As America prepares to celebrate its 250th birthday, it’s not so much “taxation without representation” at issue as it is the question of what modern taxation represents – For some, a chance to strike a blow against wealth disparity while pursuing a socialist dream of expansive government. Nowhere is that more evident than in California and a ballot initiative which, if approved by voters in November, would impose a 5% “wealth tax” on the Golden State’s resident billionaires – 90% of the proceeds going to state healthcare programs. Joshua Rauh, the Hoover Institution’s George P. Shultz Senior Fellow in Economics and an expert on California-style taxation, discusses America’s current fascination with socialism and economic class warfare as well as all that’s at stake in the Golden State. Will a voter-approved wealth tax prompt billionaires to flee California for the likes of Austin and Nashville, taking with them needed tax revenue? Would the one-time tax lay waste to Silicon Valley as an incubator of innovation (and revenue stream)? Moreover, if the promised revenue doesn’t materialize, is California likely to apply the tax to millionaires as well (and perhaps expand it beyond a five-year period, as happened a decade ago when the Golden State extended a “temporary tax” on California’s upper earners)?
