1) How much revenue will your "billionaires" talking point deliver? Using IRS data, which you can find on IRS.gov. The total taxable income of over 10 million dollars is 1.4 trillion. The term "billionaires" measures net worth, not income.
2) As I said before, the US is currently spending 23% of the GDP, which is unsustainable. The highest income the US has collected since WW2 has not exceeded 20% of the GDP, no matter the tax rate.

4) The US is a large country.
5) This is a dumb take. The National debt has exceeded 35 trillion.
6) The left-wing summer of love caused billions in damage and many deaths.
