National walls

My prediction is once Trumps wall is complete, more will be built.

Walls around cities, to keep people in/out. Homeless camps will be moved outside the walls, with ID checks for entry/exit.

If you have no valid reason for entering the city, you will not be allowed in.

Then maybe segregation of the rich/poor with access only allowed for certain people.

This would slowly be brought in with the promise it would help reduce terrorism, crime, vandalism etc but would eventually only benefit the wealthy.

I'm not saying Trump will be behind this but once the wall is built, certain people will notice the potential for control. Could be years before the idea is raised.

That's just Dumb.
