Probably looks like the slums of NYC at the turn of the last century... all those dirty Italians and Irish.
Did the Italians and Irish come in through Ellis Island or did they just stroll across the border in the middle of the night, violating all kinds of immigration and labor laws?
Exactly so. And those slums still persist a hundred years later and in many places they are now expanding out into the suburbs. Ask the people of Long Island. In the mid-1960s we started a war against poverty and as far as i know it is still ongoing and I am still paying massive taxes to pay for it. I can't for the life of me think why anyone would think it was a good idea to import more poverty.
