To me, it doesn't matter what they make. We already have a graduated tax system...just cut the loopholes. No one needs to be taxed more. (Cut spending!!!)
I do respect when people who make a lot of money choose to donate to charities (ie what you say about Biden). Donating and helping others makes the donator feel good, not just the recipient. However, when government forces donation by heavy taxation, people don't feel the same.
