they are third worlders living in the first world. they are concerned primarily with making more money and sending it back home, not integrating into american society and living like a native. they're low-skilled workers, low-skilled americans do not magically become better qualified to demand higher wages, the third-worlders entering the market are fine with working at slave labor wages because 1.) it's still much higher than they get at home due to the strength of the dollar and 2.) they are used to living in impoverished shitholes where working and sleeping is all they do. it's a net negative, all evidence points to this.
