The confusion here is that you're misusing the word "regressive". In the context of taxes, "regressive" means that the poor pay a higher percentage than the rich. That's because it's the opposite of "progressive", which means "super-linear", i.e. the rate progresses with your income. I think that what you actually meant was "progressively tax ultra high incomes".
