You as well can pay more if you wish. It will make no difference because Congreff will never curb spending ----so your money, along with Gates's and Buffett's will be sent in vain.
Buffet and Gates are hypocrites. They will say nice things to please the progressives and they want to be liked. Because people are dumb enough to think that higher taxes is a good thing, and whoever advocates for higher taxes should be admired.
A non-specific, general, overall "higher taxes" is not generally good. And btw, they didn't say that.
