Jeb Bush, Marco Rubio, and the Establishment GOP are the ultimate wealth redistributionists. They want to keep the current system... not to mention the fact that the Establishment GOP is RESPONSIBLE for establishing and maintaining the current tax regime in Washington.
Trump wants to eliminate the current tax system by eliminating deductions and implement the Fair Tax. He’s also said he likes the Flat Tax.
On Hannity this month he said he opposes both the fair tax and flat tax. I have no idea if he flip-flopped before or after that.
