The proposed California "entrepreneur's tax" is not a one-time levy on billionaires. It's viewed as the first step toward an annual tax on paper wealth, with thresholds planned to drop to $25M. This would impact founders with illiquid equity post-Series B, forcing a mass exodus before an IPO.

The implementation of wealth taxes could burst market bubbles. Since these taxes must be paid in cash, holders of illiquid assets (like stocks or real estate) are forced to sell. This forced selling creates downward pressure on prices, potentially triggering a broader market downturn.

The idea that a billionaire can "spend" their net worth is flawed. Their wealth is primarily in company stock; liquidating it would crash the price and signal a lack of confidence. This misunderstanding of wealth versus income fuels unrealistic proposals for solving global problems.

Despite voter popularity, broad wealth taxes are historically ineffective. Most OECD countries have abandoned them due to low revenue, administrative complexity, and capital flight. A more practical approach is to focus on targeted reforms like closing the carried interest loophole and taxing capital gains as ordinary income.

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.

The wealthiest individuals don't have traditional paychecks. Instead, they hold appreciating assets like stock and take out loans against that wealth to fund their lifestyles. This avoids triggering capital gains or income taxes, a key reason proponents are pushing for a direct wealth tax in California to address this loophole.

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.

Instead of taxing unrealized gains, which forces asset sales and creates economic distortions, a more sensible approach is to tax the cash that wealthy individuals borrow against their assets. This targets actual liquidity and avoids punishing the long-term investment that builds the economy.

A major flaw in the unrealized gains tax is that it punishes all investors for the actions of a few. A more targeted and less destructive approach would be to tax the loans that wealthy individuals take out against their stock portfolios, targeting the actual cash they use without harming the underlying assets.
