Taxes fall in brackets. For example, income:
https://www.nerdwallet.com/article/taxes/federal-income-tax-...* $0 to $9,950 - 10% of taxable income
* $9,951 to $40,525 - $995 plus 12% of the amount over $9,950
* ...
* $523,601 or more - $157,804.25 plus 37% of the amount over $523,600
Problem? There is effectively no taxes on wealth, only income/capital gains.
This system really screws over the middle class and immigrant families because we generally accumulate wealth through income... meanwhile Bezos can passively "earn" billions per year through his prior ownership of Amazon shares, with an effective tax rate of 0%.
The low interest rates further benefit the rich because they can take out low-interest loans collateralized by assets (that is, Jeff can take out a $100M loan to get liquidity, without liquidating $100M in shares - he only needs to sell enough to pay off interest [the portion sold is taxed as income]).
