If the US were more self-aware and honest it would expand existing guest worker programs and create new pathways for temp labor to work without obtaining citizenship the way Singapore and Middle Eastern countries do. They seem cruel but at least each side of the equation knows what it's getting and they can even visit home every year! But Americans' hubristic tendency is to look at a place like Singapore or some other new skyline in the middle east or Asia and declare smugly "borderline slaves built that."
