OK, but the article also gives multiple examples of having to hire back the same (American) worker after they left because nobody else could do it.

So either the market doesn't work at all and cannot exhibit enough demand to cause a supply to exist (perhaps the offered pay would need to be so high that the endeavor ceases to be profitable?), in which case throwing government regulation at the market to artificially restrict supply certainly won't help anything, or companies are able but unwilling to pay high enough wages, at which point we're proposing using government regulation to punish American businesses who don't work the way we want in the hope that they concede defeat, which hardly strikes me as a pro-American position - and more practically doesn't seem like a way to make American business more competitive.

Perhaps not though, in which case we don't need to follow this line of thinking to the end of the world. The US isn't lacking in college students or workers, just ones willing to work in one of the hardest majors while being treated as a commodity that includes workers from developing countries.
