The real rich don’t pay any income tax tho? Not sure what you mean. Sure the high-income developers and engineers and lawyers etc. would become a richer, but they are not the rich, are they? The owners of the businesses they work at are. And they don’t pay income taxes.
In the USA in 2021, the top 1% of earners payed 26.3% of federal income from taxes, $3,872,395,000,000 Total. The top 50% of earners payed 89.6% of income taxes.
You could argue that the "true" rich people weren't earners because they took out loans against their stocks and properties, but they're either going to sell or die sometime and that has been true for centuries. However, Elon Musk for example won't make your list if that's how you measure it because he did sell and he paid billions in taxes.
