Right.

That wasn't a thing until the middle of the 20th century.

The borders were not particularly patrolled, and then between Mexico and the United States, people just crossed.

It wasn't seriously policed, and it wasn't a big deal.

People would cross and go to work and come back.

There wasn't really a strict system for saying that somebody could work or not.

None of that existed until we start imposing restriction in our system and then militarizing it so that you have to meet with a border officer before you're able to cross.

Got it.
