The USA will no longer exist. It will have disintegrated due to repeated administrations of insane leftists who will debt us into oblivion. Then patriot reactionaries will seize a small section of the country in the ensuing chaos, and the rest descends into minor anarchy.
The world will plunge into a second Dark Age, but it will actually be a golden age of sanity.
The world has forgotten what can happen when we put idealists in charge. Maybe once the morons fertilize the fields we can live in a sane world again.
