In the 30k scenario, if they are paid bi-weekly that is ~$10 a paycheck using the Tax Foundation’s reported numbers, ~$13 with their calculator, and <$5 with my math.
It’s still an increase but even in the worst case scenario that isn’t onerous.
In the 165k scenario, in their bi-weekly paychecks they would see ~$95, ~$214, or ~$164 more respectively. Now this is much more but how much do you want to bet the Tax Foundation has an article complaining about the deficit?
