You mean, that there's a progressive tax system rather than a regressive one? Yeah, that is a triumph of decency and something we should not take for granted! This is something we should try to do MORE of.
I think progressive taxes are fine, my point was that the rich are paying their fair share.
No, because they are getting wealthier at a greater rate than either the middle class or poor. The U.S. didn't used to have this problem when the upper tax bracket rate was above 70%. It's plausible it doesn't need to be that high if deductions aren't as generous as they were when taxes were that high (for more than a generation by the way, so it's not like extremely high taxes at the top brackets has some civilization ending result - we already know it doesn't, in fact it acts as a strong incentive to avoid taxes by taking deductions in creative ways which ideally also have a social benefit).
