The claim was that personal income tax "in the US" was about 50%.
That's very different than saying the truth which is that "maximum marginal income (including payroll) tax rates in the highest-tax US states are around 50%".
> you see entry level jobs that offer salaries already at or neat the top tax brackets
The top US federal marginal rate starts at $400,001 for a single filer; $450,001 for married filing jointly/qualified widow(er), $225,001 for married filing separately, and $425,001 for head of household.
I've never seen anything fairly described as entry-level offering a salary at or near that, even in expensive places like SF.
