We shouldn't even be enforcing the border this way. You come across, you give a name, a retina photo, fingerprints, and a passport photo. In exchange you receive an ID, a tax ID number, and a booklet containing common laws and workers rights in the US. You are then pointed at the shuttle to the nearest Greyhound Bus Station.

This reduces "illegal entry" to something that only actual criminals need to do. It also solves our employment crisis in construction and agriculture. Our border agents can now focus on stopping actual drugs and criminals instead of normal people who are really scared.

But we can't do this for... Reasons. I've never actually gotten a good reason we couldn't do this.
