They are everywhere. Game over man.
I think I'm the only person in my office who knew the name of the hard-working Mexican who cleaned our offices at night, but unfortunately many of the immigrants I've seen are not like him. I used to scoff when a cowroker of mine said this would continue until they turned the USA into a third-world slum. Now I wonder if he was quite right.
But again, the blame also falls on the voters, who don't shut down the causes.
