Earlier quoted context omitted.
Please stop counting taxes of super-rich in absolute terms. It simply doesn't matter. We need percentage-based taxes to get the real picture. Because those numbers seems a rounding error given their wealth.
I think it does matter. Let's assume Musk paid $12B. How much have you paid? Isn't it then actually reasonable to say that he contributed more than you to the country, even if his tax percentage is lower than yours?
If you talk about taxes percentage-wise, you make clear that the super-rich do not pay their fair share, that they will get richer faster than everybody else and, the most important fact, that long-term stability might suffer, because the bigger the divide between rich and poor, the more civil unrest follows.
