. . look to South and Central America. We'll have the same economy they have now with a very few very, very rich, a huge number of poor and a very small middle class. That's been the primary objective of every Republican administration in recent decades and the current one is making excellent progress. Economics will do the rest.
Of course without a huge middle class buying huge amounts of consumer goods the economy will collapse in a positive feedback mode so this transition will happen very rapidly.
Look for food to become your major budget item, with meat unaffordably expensive - but Kobe grade beef will, of course, be in plentiful supply for the very rich, though you won't be allowed into the places that sell it.
The economies of Asia will also collapse because they'll be so thoroughly adicted to draining wealth from the American middle class. All those low cost but marginally profitable manufacturing complexes will close with a bang. The rising expectations of their people will not be met and there will be social turmoil.
Expect wars, lots of wars and even more wars.
