Despite a public image of libertarian self-reliance, the VC industry's success is built on government support. This includes leveraging state-funded R&D (the internet), lobbying for favorable tax laws (carried interest), and accessing pension funds through legal changes.

Mark Cuban warns that a California wealth tax would compel him to make startups leave the state as a condition for investment. This isn't just a threat of founders leaving; it's a structural shift where venture capital actively drains talent and future tax revenue from jurisdictions with hostile policies.

California is on the verge of a massive tax revenue surge from upcoming IPOs of companies like SpaceX and OpenAI. However, a proposed wealth tax on illiquid assets is causing tech leaders to relocate, potentially costing the state the very economic boom it needs to balance its budget.

When governments derive revenue directly from a hyper-productive AI sector instead of citizen taxes, their incentive to represent public interests erodes. Similar to oil-rich states, they may become exploitative or neglectful, as their prosperity is decoupled from their populace's economic activity.

Venture capitalist Bill Gurley argues a key reason for Silicon Valley's success was its physical and cultural distance from the regulatory and political influence of Washington D.C. He now sees an ironic shift, as tech giants become increasingly entangled in lobbying and politics, threatening the ecosystem that allowed them to flourish.

Threatening to confiscate wealth from the most mobile people incentivizes them to leave. This capital flight has already begun in response to the proposal, proving such policies ultimately reduce the state's long-term tax revenue by driving away the very people they aim to tax.

According to Mark Cuban, a wealth tax would trigger massive capital flight. He and other investors would require startups to relocate out of states like California as a condition of investment. This preemptive move would starve the state of its next generation of high-growth companies, destroying future tax revenue.

California's budget is dangerously dependent on a tiny cohort of high earners. The top 1,000 individuals pay $22 billion annually—over 10% of the state's entire revenue. This makes state finances extremely volatile and susceptible to the exodus of even a small number of these wealthy residents.

Abundant tax revenue from high-income earners creates a false sense of security. This surplus gets absorbed by bureaucracy, reducing the pressure for government to innovate, improve efficiency, or solve hard problems, much like a country over-reliant on a single natural resource.
