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 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.

Ray Dalio argues bubbles burst due to a mechanical liquidity crisis, not just a realization of flawed fundamentals. When asset holders are forced to sell their "wealth" (e.g., stocks) for "money" (cash) simultaneously—for taxes or other needs—the lack of sufficient buyers triggers the collapse.

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.

Bubbles are created when assets like startup equity are valued astronomically, creating immense perceived wealth. However, this "wealth" is not money until it's sold. A crash occurs when events force mass liquidation, revealing a scarcity of actual money to buy the assets.

Ben Horowitz warns against wealth taxes on unrealized gains by citing Norway's experience. The policy required founders to pay taxes on their private company's rising valuation with illiquid stock, leading to an exodus of entrepreneurs and effectively dismantling the local tech ecosystem.

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.
