Politicians who don't want to make tough choices have been saying that for decades.
Of course you can have your tax cut buddy, and of course it won't cost you anything.
It will pay for itself with growth!!
The current federal debt is $21T.
The $21 T deficit is a result of out of control spending. The federal gubmint was collecting record revenue under Obama and yet the deficit increased each and every year. If revenue was the issue I would guess the deficit should have decreased, but it did not. When the Reagan and Bush tax cuts resulted in increased revenue coming into the treasury the spending increased faster than the revenue grew. Our deficit is a spending/budget discipline problem. Once it is shown that congress is capable of operating the gubmint with the revenue collected, things will get better. The past few years it has not even been close to doing so. The deficit will not improve until that happens regardless of the taxes we pay.
