Once a 'one-time' wealth tax is implemented to cover deficits, it removes pressure on politicians to manage finances responsibly. The tax becomes a recurring tool, and the definition of 'wealthy' inevitably expands as the original tax base leaves the jurisdiction.

A provision in the proposed California wealth tax calculates an individual's net worth not by the market value of their shares, but by multiplying their voting power by the company's total market cap. This disproportionately affects founders with super-voting stock, like those of Google.

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.

Congressman Ro Khanna proposes a tax on the total net worth of individuals with over $100 million. Unlike an income or capital gains tax, this targets unrealized wealth, forcing the liquidation of assets like stocks to generate the cash needed to pay the tax.

Founder Aaron Galperin moved from high-tax California to no-tax Texas specifically to avoid state income tax on his company's sale. This pre-exit relocation is a crucial, often overlooked financial strategy that significantly increases a founder's net take-home pay from a liquidity event.

A proposed wealth tax in California triggered a significant flight of capital and high-net-worth individuals, even without becoming law. The key factor was the failure of politicians to uniformly condemn the proposal, which was perceived as a threat to fundamental property rights, signaling a hostile business climate.

Unlike a capital gains tax which is paid upon sale, Switzerland's wealth tax is levied annually regardless of performance. This prevents timing tax payments and its compounding effect can become more costly for long-term investors than a one-time capital gains tax.

While popular on the American left, direct wealth taxes have a poor track record in Europe. Countries like France, Sweden, Germany, and others discarded them because they were too complex to administer and ultimately failed to generate enough revenue to be worthwhile. This historical precedent presents a significant practical challenge for proposals like the one in California.

The proposed wealth tax applies to illiquid assets. A founder of a highly-valued private AI startup could be deemed a 'billionaire' and face a massive tax bill on paper wealth, even if their company never exits or ultimately sells for a much lower price, creating a huge financial risk.
