Quick Summary

The article discusses Proposition 40 in California, which proposes to impose a one-time tax of 5% on fortunes over $1 billion to fund Medicaid. Billionaires like Elon Musk and Sergey Brin have spent over $333 million opposing the measure, arguing it could drive wealthy individuals out of the state. The author supports Proposition 40 but argues that it does not address deeper economic issues, such as the role of public funding in creating wealth for tech billionaires. They highlight how government-funded research has underpinned innovations like Apple's iPhone and SpaceX technologies, suggesting that addressing these underlying factors is crucial for a more equitable economy.

Narrative

This is called “pre-distribution,” shaping how value is created and shared at the outset, rather than waiting for the tax code to repair the damage, and it is a crucial principle for making capitalism work for us all. But establishing this kind of capitalism requires that we commit to another principle: access for all and reward sharing.
