“America’s wealthiest families can leverage that on-paper value increase to secure favorable loans with low-interest rates in lieu of using taxable income to finance their lifestyle.”
You can do that too using a HELOC or similar. But if you have limited assets (collateral) and a lower credit rating than the wealthier you won’t get a lower interest rate on that loan offered by the banks.
Wealth is generational in nature. If you do the right things, your children will have more options than you.
