This is such a ludicrous argument but you keep making it anyway.
Where I live there are few illegal aliens, mostly legal immigrants. And restaurant tables are getting cleaned Ben, same with the toilets, the hotels, and the lettuce and tomatoes are getting picked. You simply don't want to recognize supply and demand. If there's too many restaurants and hotels that can't be properly staffed, they close or pay better wages, and market forces work themselves out. That's why in my area and Canada that have few illegals the work gets done.
But I suppose you'll keep saying it over and over we need millions of illegals till like in 1984 the lie becomes the truth.
