It won't be Trump that sells America. It will be the Koch congress.
Unless the impotent democrats vow to filibuster every single piece of legislation in the next four years, by 2020 Medicare will be a block grant program admnistered by the states. Medicaid will not exist. All new contributions to SSI will be in the form of a 401k. Abortion and chemical birth control will be illegal at the federal level. The ACA will be eliminated. The civil rights voting act will gutted. Corporate income taxes will be eliminated. The EPA, the depts of energy, education, and revenue will be disbanded. The military will be (completely) privatized. Deficits will skyrocket. Corporations and other nations will buy all the remaining US debt in the form of bonds. They will then forclose on those bonds and take the rest of the US commons in payment. The government will be bankrupt and replaced by a special corporate board that will allow elections, but only at a local level. The states will be divided up by the debt collectors.
Then the US will recognize its destiny as it officially becomes the corporate states of North America. The Republican Party will not pussy foot around. This is what they have been working on for the last fifty years. They will do so much damage in the next two years that it may be irreversible. In four, you'd better learn the corporate anthem.
