We'll always need someone outside to hate.
My guess is we're moving back to the model we've always had: An aristocracy, a merchant class and a bunch of peasants.
The political class (aristocracy) will always need an external villain to blame things on and rally the masses.
I think the circa 1776 democracy experiment has been winding down for about 50-75 years now. It won't go more than another generation or two in my opinion. When our forefathers wrecked the class system, society had continuous convection. We're undoing that convection now in the name of helping the least fortunate. It's so ironic, since the people voting them in are the ones who will be locked forever into the peasant class.
