Sure, and I'm not a "billionaires shouldn't exist at all" person, so I'm not saying we should have a 95% wealth tax on billionaires. I'm also not proposing that we fund the government solely by taxing billionaires. I'm saying we should tax them significantly more than we do now, and we should also tax multi-millionaires a lot more than we do now, and we should focus on reducing the deficit by raising revenues. We don't need to close the gap with all 6.9T in spending, we need to reduce the deficit of $800B. We should look at raising an addition 200-600B in revenue, putting the burden largely on the backs of the extremely wealthy (and not just billionaires, but if you're in a household making more than half a million dollars a year), by heavily taxing their income, capital gains, and estates. We should look at moderate reductions in our defense spending. With approaches like that we could bring our deficit down into the $100-$200B range, which would be a more reasonable steady state for us.
