Take a look at some of the soccer fans in attendance at Confederations Cup matches in Brazil.
My thoughts: The wall has a purpose. Under the pretense to keep illegal aliens, guns and drugs out. Yet, I'm sure it's going to b real hard to leave the states as an American in the future. Got a parking ticket? Can't leave. You owe taxes but want to go on vacation for 3 days? Can't leave. Got a speeding ticket? Cant leave. Going thru a divorce and it hasn't been settled until next month? Can't leave. I'm sure they'll find anything to keep people from leaving. And if people revolt because the Great Wall is being used against them? Martial law, curfews and can't leave.
