You're not responding to the GP's argument. They're saying that tax revenue has increased faster than median income, and this hasn't addressed income inequality at all. Why would taking more even faster do anything different? "If we need more tax revenue" isn't a foregone conclusion. It might be the answer but there's at least some evidence to the contrary.
