Yes, I don't have a problem letting legit people in to work - whether it's high tech jobs making semi-conductors or low tech jobs pumping out porta-shitters. However, the people coming in need to be checked.

As for the issue of border hoppers... well, since the big L libertarian party has a hard-on for using the military for strictly domestic defense, why not use the military to keep them out? You hop the border, you face the potential of getting shot. I don't know whether you're legit or some haji supporter delivering biological material to build a bomb, and frankly, I'm not gonna chance it.
