Lets conceed that what you're saying is true (I didn't check but don't find it unebelievable). "Percentage of taxes are paid by the top %1" is just one metric, but there's no reason why we should consider it the only criterion. I would argue that in our world what you said might be true, and at the same time the bottom 90% lives their day to day with the threat that if they disobey their employer, their lives might quickly fall apart, and I would further argue that the latter is more telling about fairness in our society, than "top 1% pays more than bottom 90%"
