California Billionaire Tax Defeated

California voters rejected Proposition 40, defeating a measure that would have created the nation’s first wealth tax on residents with a net worth exceeding $1 billion.

The Associated Press determined the outcome on Monday after a slow count of mail-in ballots.

The rejected initiative would have imposed a one-time 5 percent levy on personal assets for billionaires residing in the state. Proponents intended to direct the bulk of the generated revenue toward health care and education programs.

Record-Breaking Opposition Spending

Opponents of Proposition 40 mounted a massive campaign funded by prominent technology billionaires. Google co-founder Sergey Brin contributed more than $100 million toward defeating the wealth tax, according to The Associated Press.

Business Insider reported that opposition groups raised over $300 million in total. This massive war chest financed an extensive television ad campaign that outspent supporters by a wide margin.

California Democratic Leaders Split over Wealth Tax Measure

While the California Democratic Party endorsed the measure, top state leaders split on the issue. Democratic Governor Gavin Newsom opposed the wealth tax, arguing it would drive entrepreneurs out of the state.

Supporters relied on social media and influencer campaigns to rally voters. Dave Regan, head of the SEIU-United Healthcare Workers West, stated that the billionaire-funded attacks produced a lot of confusion and a lot of second-guessing among people who really in their hearts know what the right thing to do is, as reported by The Associated Press.
