As many posts have pointed out, the federal tax system is more progressive than many people believe. Higher-income people do pay higher rates and bear a larger share of the tax burden than people with lower incomes.
Congressional Budget Office The Distribution ofHousehold Income, 2022 :
The average federal tax rate for households in the lowest four income quintiles increased in 2022, largely because of the expiration of two policies—the recovery rebate credits and expanded child tax credit—that reduced average tax rates in 2020 and 2021 for all quintiles (though households in the top quintile were generally less affected). Without those two policies, federal tax rates would have remained more stable from 2019 to 2022. Despite increasing in 2022, the average federal tax rate for each income group declined over the 1979–2022 period. The decline was largest for households in the lowest quintile and smallest for households in the highest quintile.

The share of federal taxes paid by households in the top quin tile increased from 55 percent in 1979 to 70 percent in 2022. Most of that increase is attribut able to the change in the share of federal taxes paid by the top 1 percent of the income distribu tion, which grew by 13 percentage points—from 14 percent in 1979 to 27 percent in 2022
