I’d be OK with that if the rate was 3% instead of 10%.
Given that almost everybody lives in a state, the only thing the federal govt should be doing is protecting the borders and fielding a military.
Local taxes should be highest, followed by state, with the Feds a distant 3rd.
I would agree 3-5% is enough tax, and the only thing federal government should be in charge is defending borders, national interest and interstate roads.
