So using your numbers, the top percent of the top percent pay 1/8 of the taxes that the top percent pay, and the remaining 99% of the top percent pay 7/8 of those taxes.
That is still quite disproportionately more.
I pay a big chunk of my income in taxes too. Everyone needs to contribute. There's not enough money otherwise, and demanding that Bill Gates pay more, as much as I dislike him, isn't going to do it (and doesn't seem fair as he's already paying his fair share).
The top 1% - minus the top 0.01% - are paying 35% of all income taxes. The top 0.01% themselves are paying another 5%. The bottom 99% are paying the remaining 60%.
