The USA used to have open borders, but now Americans want to live in a country like North Korea.
Americans scream that they hate illegal immigrants, but Americans think that the US can kick out illegal aliens without having a police state.
Do you really believe that the government can get rid of illegals without having a wall, concentration camps, checkpoints, immigration raids, license plate readers, DNA collection, and NSA wiretapping? Do you honestly think that Americans are never arrested by the Border Patrol?
