To grasp the full horror of this from a financial and economic perspective you have to look closely at Trump's Gettysburg address. Where, unlike Lincoln, he threatened the women accused him sexual abuse 
On taxes he wants to reduce the top rate to 15 percent, capital gains taxes to 15 percent and overseas earning to 10 percent. Big giveaway to the wealthy. But we have actually been down that road before. Remember Bush lol tax cuts? Even before the recession all they created was unusually slow growth. 
On his trillion dollar infrastructure plan. He wants to do it through "public private partnerships, with tax incentives". And it's "revenue neutral." Confused? That's a pretty good description of every Trump position. But in this case you need to understand that  "tax incentives" are always checks written by the government when someone does something that qualifies. Build a bridge get a check. and elsewhere he cuts marginal tax rates to 0. It is one giant scam. One He will make big $s on.
