One of the criticisms I've heard first hand is that, in terms of construction jobs, that the illegal immigrants work harder than Americans and that is a major reason construction foremen hire them.
How many high school kids in the summer would like to pull or hoe weeds 8 hours/day? Someone has to do it. And don't forget about that cheap chicken at various mass outlets. Someone had to process them. If we drive all the illegal immigrants out of the country it is safe to say produce prices would shoot up at least 10% on average.
