The super-rich avoid capital gains taxes by borrowing against their appreciating assets instead of selling them. This allows them to fund their lifestyle tax-free. Since assets are only taxed upon sale, this deferral becomes permanent if they hold the assets until death, when the cost basis resets for heirs.

Not all debt is negative. Using leverage to acquire assets that generate returns—like real estate, inventory, or business investments—is a smart wealth-building tool. Conversely, financing depreciating lifestyle items ('flexing') creates a financial hole that's nearly impossible to escape.

A key principle of "old wealth" is using debt with an interest rate below market returns to grow money exponentially. Conversely, "new wealth" challenges traditional wisdom by recognizing that in many markets, renting and investing a down payment can yield higher returns than home ownership.

The traditional 30-year mortgage for a primary residence is a suboptimal wealth-building tool. A more effective strategy involves securing long-term, non-callable debt to purchase productive, cash-flow generating assets, rather than tying up capital in a personal home.

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 US tax system heavily favors owners over earners. Earners are taxed annually on income, limiting compounding. Owners, holding appreciating assets like stock, can defer taxes indefinitely by borrowing against their assets instead of selling them, leading to exponential wealth growth.

Economist Arthur Laffer argues that debt is merely a tool. Debt used for productive investments that generate high returns (e.g., Reagan's tax cuts to spur growth) can be beneficial. In contrast, debt used for non-productive purposes (e.g., paying people not to work) is destructive to the economy.

Thinking about leverage as simply "on" or "off" is limiting. A more advanced approach views any asset with a lower expected return as a potential liability. One can effectively "borrow" it (i.e., short it) to finance the purchase of an asset with a higher expected return, aiming to capture the spread.

Profitable companies act as a hedge against currency debasement. They issue long-term debt at low fixed rates, effectively shorting the currency. They then invest the proceeds into productive assets or their own stock, which tend to outperform inflation, benefiting shareholders.
