Alternative for the slider change on (progressive) income tax, could you rename flat tax to “Flat Income Tax”, having as-is, and “Progressive Income Tax” have an option to move 4 staggered ‘bracket markers’ (the cost being to move one, or multiple at once). I know the devs seem to not like stating specific numerical earnings, so the sections created by the bracket markers could be for Low, Lower-Middle, Upper-Middle, and Wealthy earners. The top marker (showing the % paid on ultra-high earnings) would have to be lower than 100% minus the flat income tax rate of course.
