I personally feel a moral obligation to pay my fair share of taxes, especially if I expect my community to be a place I want to be. I could itemize more stuff and pay less but I'm in a position where I can still live comfortably taking the base deduction. In my opinion ultra rich people should be doing the same whether the rules change or not.
How do you decide what your fair share is though? Do you not take any deductions, even the standard deduction? I'm happy to pay my taxes in full too, but I pay my rate for what they say my income is, including applicable deductions to that income. That's what the billionaires do too. They just have way more tools available to them.
The "ultra rich" likely have a different perspective into how tax dollars are continually squandered and abused, which tempers their desire to give it away to some of the most inefficient and corrupt organizations on the planet.
If you feel so strongly about giving your money away, nothing stops you from writing a check to your favorite causes.
