If the rich get to keep more of their money, through tax cuts, who is going to pick up the burden ?
To add more. Proportion of income taken is much more important as a measure of impact than the proportion of the total contributed by any group. (And it also matters how much is being collected)
Even then, the rich can afford to give a higher proportion of their income, because basic expenses have to be paid by everyone (housing, food, clothes)
And then there are other taxes, too. Shifting the tax burden from income tax to others is one way that the burden can be shifted - which won’t show in your figures because they only show the proportion of Federal income tax each group pays.
