What’s good for the goose is good for the gander, no one expects the very poor to pay more than 1 percent, which will be enough to give them skin in the game.
And set the next higher bracket at $24,000 with a current normal percentage, and follow suit on up to the highest bracket.
Sure, 1 percent ain’t much but with a 320 million population it's not chicken feed either, plus the poor won’t be going along in this great country just for the ride.
Without paying any stake in federal income taxes why should those masses of hardcore liberal voters give a damn about the country or how high the tax rate goes. You can't bond with anything you're not invested in.
