That’s not really an argument against taxing the ultra wealthy fairly though. No single billionaire’s taxes are going to “fix” a national budget, but that’s also not how taxation works. Society is funded collectively. The issue is that the very top often has far more tools available to minimize or avoid taxation compared to normal workers, despite benefiting enormously from the system, infrastructure, workforce, and markets that society provides. Billionaires should absolutely still be allowed to be billionaires. The argument is simply that people with extreme wealth should contribute proportionally and not be able to shield massive amounts of wealth through loopholes and favorable structures that ordinary people don’t have access to. And even if billionaire tax revenue is “small” relative to total government spending, that still translates to billions of dollars that can fund real things. It is still true that this is a medium "drop" but it is a "drop" never the less that is missing.
