Actually, some of my resources in Argentina have better English language skills than most of my US resources. It'll all work out in the long run, though, as wages here in the US balance out with the rest of the world.
Most of the Hispanic immigration in my area is not from the “Southern Cone” (very European, and better-educated); they are from the Andes to the north and Mexico. In those countries, the better-educated now can often make a living there, and it is part of the lower class that emigrates.
