Welcome to the reality of communism: faced with the reality of its failings, it must prevent people from leaving.
That’s why I’m nervous about the Right’s shrill calls for a border fence: fences stop movement _both_ways_.
It’s not as if you could “hide in the shadows” if you slipped across the border into Mexico. What, you’re going to do a job Mexicans won’t do??You don’t want to hear the blood-curdling response you’d get if you proposed that we make Mexico’s immigration policy our own.
