The rich used to pay a reasonably fair share of the taxes to run this government but there is a new picture now. It is the rich who borrow money to the government to pay for the deficit and other expenses. In return the tax payer pays them (the rich) with high interest added. So when they get a tax cut like the one they just got it is a win-win situation for them while we get nothing but a higher bill.
This explains why they are not worried about the cost of unending wars and other none needed items such as the stupid wall on the border. The more the government borrows from them the richer they get. And inversely, the poorer we get.
