Border defense shouldn’t be confined to the border:
For many years it was a reasonable fear you could be at a company in the USA interior, working illegal, and ICE/BP would show up, grabbing people.
Invasion shouldn’t involve sweating it across the border, then being “home free” in the interior.
They should always have fear in the back of their minds of being picked up.
In Japan all foreigners are required to carry a Foreigner ID Card at all times.
You need it to register a bike, to rent DVD’s, to visit a clinic or the hospital or dentist, you must show it for very many things.
Japan is the 3rd biggest economy and grappling with a shortage of young, strong people yet the total number of illegals is probably 0.5 million, mostly Chinese and Koreans.
Things would really start moving if at some point we start arresting and punishing officials of the companies who hire illegals. The higher the official, the better. They need to require e-verify and get things in place so that the company officials can be held liable for employing illegals.
