This is a transparently misleading framing.
The very wealthy are paying very low effective rates on their investment gains. Various billionaires have publicly described the truth of this. This is not 20% on top of 35%. They are paying a marginal rate of 35% of deliberately minimized taxable income and zero on deliberately maximized unrealized gains. Then 20% when realized, but as we all know by now there are ways to make sure it’s never realized.
I don’t know what the best approach is here, but I know this framing is nonsense.
