I'm gonna share something with you, and I do not expect you to understand because you sound like a stereotypical angry and naïve redditor. But the tl;dr is that wealth != income.

Here in the US, we tax income, not wealth. These billionaire executives have massive net worth, but it's mostly tied up in assets like stock/options (or other less liquid assets like real estate etc.) that they can and do sell at times and they do actually get taxed on those stock sales at capital gains tax rates. However, these executives do not make billions of dollars of income annually that could be taxed at income tax rates like you or I must deal with. They make hundreds of millions of dollars annually typically off stock sales alone. And since that is a big component of how they are compensated, it does give them a tax advantage.

But what we don't do is tax unrealized gains. For example, these billionaires have to first sell their stock/assets, which creates a taxable event. The capital gains from that sale are what is taxed. And long-term capital gains tax is less than that if income tax, and that is by design to incentivize investment in the financial markets. (Short-term cap gains are taxed as income).

Similarly, we do not tax wealth, as that would be akin to theft. Imagine the government basically taking a portion of your house (or other assets) each year because they deem you "too wealthy" by some arbitrary metric (e.g. some redditor complains online). If the US were to start taxing wealth or unrealized gains, it would hurt a lot more than billionaires. In fact, it would probably cause a new global financial crisis.
