It isn't even the labor. It's the votes. They see 11million potential voters and don't want to have them AND their legal resident families and those who share their heritage to become another 98% Democrat voting block.
Democrats have no problems with employing these people below minimum wage either. Look at the Clinton appointees who harbored illegal immigrants to work in their homes.
I don't buy that. Doesn't make real sense and they've come clean on wanting cheap labor.
