Yeah this argument is so silly: "the top 1% pay 60% of income tax" oh okay, so as they get closer and closer to escape velocity from the rest of us, that number will climb to 1% paying 70%, then 80%, then 90%, so your argument to tax them gets weaker while the functional need to tax them gets stronger.
The top 1% pays 24% of Federal taxes, and the bottom 50% pays somewhere between 7% (bottom 40%) and 16% (bottom 60%).
