“Its about cheap labor for big business, nothing more.”
I don’t buy this argument. Take a look at the Fortune 100 and try to find a company that would need uneducated, illegal alien employees.

Probably not “big business” but a lot of manual labor, including agriculture, construction and meat packing.
