If he cuts taxes and gets government on the right track to start cutting spending, then where would the deficits come from? Biggest problem we’ve had for the last few decades, at least, is a bunch of people that don’t know squat, writing checks knowing that it doesn’t matter if there’s nothing there. They’ll just keep raising taxes or borrowing for their pet projects.
With Trump, being the business guy that he is, knowing how to squeeze every last penny to make a buck, he just might be able to pull it off. Of course, getting rid of as many illegals off the government boob will be a fantastic start.
It's the cutting spending that is the unknown. Trump needs to start detailing those. We currently run a budget deficit of $300 to $400 billion. According to this article the tax plan will increase that by another $300 billion. We know that Trump is advocating increases in defense and infrastructure spending. Close to three quarters of a trillion dollars needs to be cut from spending.
