I agree with you and your proposal with the exception of 5 figure income having no income tax. At a billion level it might not be so important the difference between one or two billion. But on the 5 digits salaries, the difference of someone making 30k or someone making 80k is definitely meaningful. And as someone being in a comfy point in between there I do think everyone in my bracket should be paying taxes. Not high, but definitely something. Then lower incomes then yes, definitely 0% tax. But the amount of people on 5 digits salaries that are on the higher end is definitely worth having some tax, even when a small amount it already helps support the system with so many.
